Economic inequality has emerged as one of the most pressing social issues of our time, particularly in the United StatesSince the 1980s, there has been a dramatic shift in the distribution of income that has resulted in a significant concentration at the top of the economic pyramidBy 2014, the share of income earned by the top 1% of earners in America nearly doubled, rising from 10.7% to 20.2% of total pre-tax national incomeThis group largely consists of corporate executives, lawyers in high demand, financial professionals, and wealthy families that rely on investment incomeEven more staggering is the income growth for the top 0.1%, whose share of national income surged from approximately 1% to around 5% within the same timeframe.

Such exacerbation of inequality within the U.Scannot be fundamentally attributed merely to the natural outcomes of technological advancements or globalization; instead, it is deeply rooted in the rise of finance-driven economies since the 1980s

This shift has unfolded through three interconnected mechanisms that have facilitated the reallocation of national resources away from productive sectors and households, causing an upward spiral in inequality without corresponding economic benefitsBy steering corporate focus toward financial markets rather than genuine production, the reliance on labor for profit generation has diminishedConsequently, the risk of economic uncertainty has transitioned from organized societal structures to the shoulders of individual families, significantly increasing their dependency on financial services.

One major factor contributing to this trend is the evolution of banking, which has fundamentally transformed how financial institutions operateIn the early 1980s, non-interest income accounted for less than 10% of the total revenue of U.Scommercial banks

However, this figure climbed steadily, reaching over 35% by the early 2000sThis shift indicates that today, banks derive more than one-third of their total income from non-traditional banking activitiesFor instance, prior to the financial crisis of 2008, JPMorgan Chase generated approximately $52 billion in interest income, with non-interest income nearing $94 billion, over half of which stemmed from investment banking and venture capital businessesSimilarly, in 2007, Bank of America reported that around 47% of its total income was derived from non-interest streams, including fees from deposit accounts and credit card services.

As American companies increasingly shifted their focus from traditional manufacturing to financial activities, the pursuit of financial assets took precedence over investing in stores, factories, and machineryThis drastic change has diminished the value of labor in profit-making endeavors, thereby altering the corporate landscape in which consumers of products are no longer the primary focus, but rather, investors in their stock

Historically, U.Snon-financial industries have maintained a tradition of providing some level of financial servicesGeneral Motors, for instance, became the first automaker to offer loans by launching General Motors Acceptance Corporation in 1919 to assist customers and dealerships in purchasing automobiles, prompting competitors like Ford to establish Ford Credit in 1959 and Chrysler to follow suit in 1964.

Throughout this diversification, finance evolved from a simple accounting practice into a sophisticated decision-making scienceCompanies stopped concentrating on specific sectors; instead, financial professionals began to supplant industry specialists in executive rolesAs a result, each unit of a company was treated as a financial asset, evaluated based on profitability to determine expansion or downsizing decisionsThis shift in management dynamics, coupled with shareholder value movements amplifying the thirst for immediate profits, led companies to prioritize rapid growth even amidst slower economic conditions.

Some corporations have even emulated hedge funds by channeling significant funds into speculative trading on financial markets

A prominent example is Eddie Lampert, who, after merging Sears and Kmart in 2005, used the cash flow from retail operations for speculative tradingBy the year preceding the 2008 financial crisis, Sears drew one-third of its pre-tax profits from such financial speculation, earning Lampert accolades as the next Warren Buffett at the time.

Moreover, Enron, prior to its collapse in 2001, had pivoted from being merely an energy company to a major player in commodity futures and derivatives tradingEnron established a power trading market that managed billions of dollars daily in commodity futures transactionsA Wall Street analyst estimated in 2000 that nearly 40% of S&P 500 firms’ earnings came from lending, trading, venture capital, and other financial activities, with one-third generated by non-financial firms.

The rise of finance has distinctly magnified economic inequality across the U.S

Families’ debts have surged alarmingly, making it a critical factor in this equationPrior to 1980, American household debt averaged around 65% of disposable incomeOver the subsequent two decades, household debt escalated consistently, even surpassing 100% of disposable income in 2002. This trend continued, peaking at a historical high of 132% during the onset of the Great Recession in 2008. While middle-class families accumulate less wealth compared to the wealthy, they often find themselves more capable of accessing credit than those in lower-income brackets, leading many into precarious debt levels during the financialization era.

A mere 10% of American households currently possess about 80% of the stock market's value, starkly illustrating the deepening divide in wealthThis financialization phenomenon has drastically altered the landscape of household wealth in the U.S

Over the last quarter-century, wealth inequality has noticeably intensified, with fewer and fewer American families able to accumulate wealth over the long termAs a result, capital has concentrated in the hands of a select few, widening the chasm between the wealthy and everyone elseFinancial assets play a pivotal role in this wealth gap, with wealthier households seeing an increasingly larger proportion of their portfolios comprised of stocks and bonds.

The evolution of wealth inequality resembles a clear U-shaped curve over the last centuryAt the turn of the 20th century, wealth was strikingly equitably distributed, with the top 1% of households commanding roughly a quarter of national wealthFollowing the Great Depression in 1929, alongside the destruction wrought by two World Wars, large-scale disruptions in wealth distribution occurred, temporarily lessening the gap between rich and poor

Wealth inequality remained relatively low through the 1950s to 1970s when the bottom 90% of households increased their share of national wealth from 20% to 35%. However, a reversal began in the 1980s, with the spoils of U.Seconomic growth increasingly captured by the wealthiest 20% of families, despite continued overall economic expansion.

Wealth is now more concentrated among the ultra-rich, who are able to hand down resources and opportunities to their offspring, thus perpetuating the cycle of privilegeThe term "opportunity" refers to the resources and chances one receives, which fundamentally shape quality of life and the capacity to alter one's circumstancesSince 1970, investments by wealthy families in areas such as childcare, education, and support for young children have tripled, creating stark developmental disparities between children from affluent and less wealthy backgrounds

This rich-get-richer dynamic has morphed into a scenario where the wealthy not only win the battle but also control the game.

The top 1% can afford to allocate more capital to the financial markets, exacerbating the wealth gap even furtherSociologist Lisa Keister's research indicates that wealth concentration among the elite is partially due to the differing investment strategies adopted by middle to upper-class individualsWealthy families can endure market fluctuations, hence are more inclined to invest in high-risk, high-reward assetsThe financial boom that began in the wake of financialization has provided exceptional returns to such families, while the middle-class tends to invest primarily in real estate, yielding lower returns and liquidity challenges.

As wealth inequality widens, differences in asset allocation become more pronounced

In the top 1% of households, business interests constitute approximately 37% of total assets, reinforcing that owning a business remains a primary source of wealth for this demographicHowever, since the mid-1990s, financial assets have surpassed business interests in overall importance, rising from 32% of total assets in 1989 to 42% in 2016. During this period, stocks doubled from comprising 12% of total assets to 25%, while the share of physical assets like cars and homes declined from 30% to 20%.

The other 90% also demonstrate similar trends regarding asset compositionBetween 1989 and 2016, stock ownership in this tier rose from 10% to 28%, with the share of total financial assets increasing from 36% to 51%. In contrast, tangible assets such as automobiles and real estate fell from 45% to 34%. The next 40% of households reflected similar patterns: stock ownership surged from 6% to 15%, and total financial assets increased from 27% to 35% during the same period.

In stark contrast, the lower half of households faces a drastically different reality

According to the research by Lin and Nilly, stocks as a percentage of assets among these families increased from 2.5% to 5.3%, while their total financial assets decreased from 20% to 18%. Non-financial assets still dominate their wealth composition, accounting for around 80%. Consequently, these families lack surplus funds to invest in improving their futuresOften, their initial investments revolve around securing a home or a vehicle, necessary for stable living yet inadequate for wealth accumulation.

When examined from the realm of overall wealth distribution, stock ownership remains glaringly concentrated among the affluentThe top 1% of American households control about 40% of the stock market, while the subsequent 9% hold an additional 40%. The bottom 90% collectively possess merely 20% of this crucial asset classThe wealthiest families are heavily invested in stocks, actively delegating an increasingly larger proportion of their investments to professional fund managers

Over the past three decades, the share of professionally managed stocks owned by affluent households escalated from 40% to 75%, while the proportion of directly owned stocks among the bottom 90% of families remained stagnant around 10%.

This disconnect between wealth and income has shaped significant dynamics within economic discourseThe accomplished economist Thomas Piketty has dedicated decades to analyzing historical trends surrounding wealth and income distributionThrough meticulous observation of the wealth inequalities that burgeoned from 19th-century Europe up to World War I, combined with recent explosions of wealth among the global elite, he elucidates an essential conclusion: over the long run, returns on capital outstrip economic growth ratesThis disparity contributes to persistent gaps in initial capital that only intensify over time as capital holders reinvest their income to sustain living standards, stacking up wealth beyond imagination.

Piketty's arguments resonate profoundly with findings from Lin and Nilly’s research

In societies with the greatest wealth equality, the wealthiest 10% commanded approximately 50% of national wealthBy contrast, since 2010, the wealthiest have taken hold of around 60% across numerous European nations, particularly Germany, France, the UK, and ItalyThe most shocking revelation lies in the observation that half the population essentially owns next to nothing, with the poorest 50% often holding less than 10% of national wealth, typically not surpassing 5%. In France, the richest 10% hold 62% of total wealth, while the poorest 50% retain a mere 4%. In the U.S., the top 10% control 72% of the nation's wealth, contrasted with the bottom half possessing just 2%.

Wealth accumulation’s escalating concentration generates a distressing reality: most individuals are completely unaware of the extent of this phenomenonMany perceive wealth as an abstract or mystical entity, highlighting the crucial need for systems research into capital distribution and its ramifications

Even within the elite’s upper tier, inequality runs rampantThe wealth shares of the top 1% generally hover around 25%, while the remaining 9% account for about 35%, underscoring an exceptional disparityDuring the explosive growth periods of the 1970s and 1980s, the wealth accrued by the top 1% skyrocketed.

The discrepancy in wealth composition amongst different layers of the wealthy class shows that nearly every household in the upper 10% owns property; however, as wealth increases, the significance of property wanes drasticallyIn the top 1%, financial and business assets outstrip real estate holdings significantlyThis is a stark contrast to middle-class families, where real estate investments remain predominant, showing that true wealth is chiefly derived from financial and business assets rather than mere real estate.

Between the poorest half and the wealthiest 4% lies a middle class of 40% holding merely 35% of the national wealth

Sadly, this middle tier mirrors the impoverished bottom 50%. The shared financial frailty indicates that true middle-class existence may no longer exist, as many possess virtually nothing save for their immediate needs, while the overwhelming majority of societal assets belong to a few elite individuals.

The dichotomy of wealth concentration can form “super hereditary societies,” where inherited wealth defines socioeconomic structuresIn such contexts, the top 4% may control as much as 90% of total wealth, with the top 1% holding 50%. Alternatively, it may yield “super elite societies” characterized by substantial income stratification driven mostly by salaries rather than inherited assetsThis labor-income inequality follows elite logic and could signal a future rife with intensified disparities, possibly exceeding historical conditions.

As the income levels are gradually elevated, the reliance on labor-generated earnings diminishes correspondingly

Currently, capital income has surpassed labor income, observed primarily among the highest 0.1% income bracketFor example, capital income among the top 10% contains substantial proportions from dividends and interestLooking specifically at France, while the middle 9% maintains capital income ratios around 20% since 1932 and through 2005, this figure shoots up to 60% among the top 0.01% income earners, with most of the income for the top 1% stemming from capital sources, especially interest and dividendsThis scenario suggests that substantial asset ownership is pivotal for reaching the upper echelons of income earners, solidifying capital's dominion.

Among the vital economic mechanisms behind this phenomenon is that asset management benefits from scale economies, implying that larger asset sizes lead to higher average returnsFor affluent investors, the capacity to embrace risks far exceeds that of average individuals, allowing them to remain steady amidst market fluctuations

Over recent decades, wealth controlled by the top-tier has rapidly escalated due to these dynamics, amplifying the disparities between the richest and the less fortunate.

Should the wealthiest 0.1% earn an average annual investment return of 6%, while global average wealth growth remains at approximately 2%, projections reveal they could accumulate roughly 60% of total global wealth over 30 yearsEven with a reduced investment yield of 4%, their share could still reach 40%. The upward momentum of wealth concentration continually surpasses any efforts towards global equity or wealth dissipation, meaning the affluent population's wealth share grows disproportionately influenced by the wealth of the ultra-rich.

Once wealth surpasses a predetermined threshold, it escalates rapidly, regardless of whether the affluents continue active job participation

For instance, between 1990 and 2010, wealth accumulated by Microsoft founder Bill Gates swelled from $4 billion to $50 billion, while L'Oréal heir Liliane Bettencourt's wealth multiplied from $2 billion to $25 billionRemarkably, both witnessed growth rates averaging 13% annually during this period, translating into an inflation-adjusted increase of around 10-11% per year, showcasing how even those who never worked still enjoy proportional wealth growth on par with high-profile entrepreneurs.

Consequently, once wealth takes shape, capital grows along its innate trajectory, and provided a sufficient scale is achieved, wealth may sustain high growth rates for decadesOnce assets eclipse specified thresholds, they leverage management advantages, thereby enhancing both risk control and scale economics, ensuring that the vast majority of returns can be reinvested

This foundational and crucial economic mechanism significantly influences long-term wealth accumulation and distribution.

To encapsulate, economist Simon Kuznets theorized a “Kuznets curve” in 1953, suggesting that inequality can be explained through a bell-shaped curve across various contextsPiketty critiques this notion, attributing it largely to erroneous interpretations and observing it lacks empirical strengthInterestingly, researchers such as Li and Nilly, and Piketty himself have yet to depict this extreme inequality accurately, recognizing it as a typical power-law distribution instead.

This power-law distribution, marked by the Matthew effect, underscores the reinforcing cycle of “the rich get richer, while the poor get poorer.” Undoubtedly, this extreme inequality has triggered numerous significant challenges, but this is a broader discussion beyond the current scope
