I do enjoy the industry I am in. Any piece of data more than five seconds old is considered out of date. Against that backdrop, I read with interest Joseph Stiglitz's book, The Price of Inequality. The book would be considered dated so I was curious if it stands the test of time.
His argument, as I understand it, is that rising U.S. income inequality is not simply the result of market forces or technological change, but largely the product of political and institutional decisions that shape markets and distribute power.
Stiglitz’s central claim is that inequality is created through the interaction of economics and politics. Governments set the “rules of the game” — taxation, corporate governance, education policy, competition law, and social spending — and these rules can either reduce or amplify inequality. In recent decades, he argues, many policy choices have systematically benefited top earners and wealth holders, reinforcing inequality over time.
A major concept in the article is rent-seeking — earning income by manipulating policy, market power, or institutional rules rather than creating new wealth. Examples include monopoly power, executive compensation structures, subsidies, weak antitrust enforcement, predatory lending, and regulatory capture. Stiglitz contends that some of the largest fortunes arise from exploiting market imperfections or political influence, not purely from productivity or innovation.
This certainly resonated with me and also made me curious. Did I not learn about the "Titans of Industry" who made their fortunes by creating something? Is the way to wealth now just to tweak the tax code? Curiouser and curiouser.
The article also challenges the traditional marginal productivity theory of income distribution, which holds that people earn according to their contribution to output. Stiglitz argues this theory cannot fully explain modern inequality because power, policy design, and unequal access to education and opportunity strongly influence outcomes.
His conclusion is cautiously optimistic: because inequality is constructed through policy and institutions rather than inevitable economic laws, it can also be reduced through different policy choices, such as stronger competition policy, progressive taxation, improved corporate governance, and expanded educational opportunity.
Again, his book is dated so does it stand the test of time? What research my non-economist brain has been able to come up with says, "Yes".
First, the empirical backdrop broadly supports his premise that inequality has been structurally rising over decades. U.S. income inequality increased substantially from about 1980 onward, with the income Gini coefficient rising roughly 20% between 1980 and the mid-2010s. More recent data shows inequality remains elevated: the U.S. household income Gini coefficient was about 0.47 in 2023, up from roughly 0.43 in 1990, indicating a persistent long-term increase in dispersion of income.
Wealth concentration has followed a similar pattern. High-income households have accumulated wealth faster than others for decades, reinforcing the concentration of financial assets at the top of the distribution. Contemporary reporting shows this pattern continuing: for example, recent analysis found that the wealthiest households are driving most consumer spending growth, while lower-income households face higher inflation burdens — a “K-shaped” recovery dynamic.
Second, Stiglitz’s claim that policy choices shape inequality maps directly onto current fiscal and regulatory debates. For example, the ongoing U.S. tax-policy discussion (especially around extending or modifying provisions of the 2017 Tax Cuts and Jobs Act) explicitly centers on whether tax changes would increase inequality or shift the tax burden toward high-income households. This is essentially Stiglitz’s “rules of the game” argument in practice — taxation, transfers, and public investment decisions determine how market income translates into disposable income. I would suggest the latest tax cut from July 2025 is going to exacerbate this trend.
Third, recent data shows that inequality can move in response to temporary policy interventions, which reinforces Stiglitz’s institutional view. Pandemic-era policies like stimulus payments and the expanded Child Tax Credit reduced inequality temporarily, while the expiration of those policies contributed to renewed disparities in post-tax income distribution. That pattern is difficult to explain using purely technological or productivity-based explanations alone.
Stiglitz’s framework is not universally accepted, but it has become mainstream in policy economics. Even economists who emphasize technology, globalization, or skill-biased wage changes generally agree today that institutions and policy design strongly influence how inequality evolves. The disagreement is less about whether policy matters and more about which policies trade off efficiency, growth, and equity most effectively.
Is the US serious about tackling inequality? In other words, can we spare some change?
My guess is that the U.S. is politically aware of inequality but structurally constrained in addressing it.
There is clearly public concern and policy attention. There have been recurring debates over tax progressivity, student debt relief, minimum wage laws, antitrust enforcement, healthcare costs, and retirement security. Both major parties now acknowledge inequality as an economic issue, which was not true in the same way in the 1990s. Perhaps that is progress or is that akin to watching paint dry?
However, willingness to act and capacity to implement durable policy changes are different things. Three structural forces limit major redistribution or institutional reform:
First, political polarization and institutional veto points. The Senate filibuster, divided government, and narrow congressional majorities make large structural reforms difficult to sustain. Most inequality-reducing policies in recent years (for example, pandemic transfers or the Child Tax Credit expansion) were temporary rather than permanent.
Second, interest-group influence and path dependence. Policies that shape inequality — tax treatment of capital income, housing supply regulation, employer-based benefits, retirement tax incentives, and higher-education financing — are deeply embedded and politically defended. This aligns closely with Stiglitz’s “rules of the game” argument: once rules produce winners, those winners resist change. And why would they want to give up their lofty perches? I have often joked that all Congresspeople should be required to have the logos of their lobbyist sponsors prominently displayed on their clothing. At least that way you will know why they voted the way they did!
Third, American political culture prioritizes growth and opportunity narratives over redistribution. Compared with European economies, U.S. voters tend to tolerate higher inequality if they believe mobility and entrepreneurship remain possible. Whether that belief matches reality is heavily debated. An interesting take on whether there is true upward mobility in the US is presented by Yale-educated Professor Xue Qin Jiang.
The Parting Glass
The U.S. will likely pursue incremental inequality policy, not structural redistribution. Expect adjustments through:
tax credits and targeted transfers,
healthcare and education subsidies,
labor-market policy (wages, bargaining power),
antitrust enforcement.
But large shifts — for example, wealth taxes, major tax-code restructuring, or European-style social insurance expansion — remain unlikely without a major economic shock or political realignment.
A side note for my fellow 401k advisors: The U.S. often addresses inequality through asset-building policy (401(k)s, IRAs, homeownership subsidies) rather than direct redistribution. That approach reduces political resistance but also tends to benefit higher earners disproportionately, which keeps the inequality debate alive.
