This excellent article in The Atlantic by Rogé Karma should be widely read. Something changed radically in our economy and our society in the past several decades, limiting access to “the American Dream.” He explores the reasons why.

He writes:

If there is one statistic that best captures the transformation of the American economy over the past half century, it may be this: Of Americans born in 1940, 92 percent went on to earn more than their parents; among those born in 1980, just 50 percent did. Over the course of a few decades, the chances of achieving the American dream went from a near-guarantee to a coin flip.

What happened?

One answer is that American voters abandoned the system that worked for their grandparents. From the 1940s through the ’70s, sometimes called the New Deal era, U.S. law and policy were engineered to ensure strong unions, high taxes on the rich, huge public investments, and an expanding social safety net. Inequality shrank as the economy boomed. But by the end of that period, the economy was faltering, and voters turned against the postwar consensus. Ronald Reagan took office promising to restore growth by paring back government, slashing taxes on the rich and corporations, and gutting business regulations and antitrust enforcement. The idea, famously, was that a rising tide would lift all boats. Instead, inequality soared while living standards stagnated and life expectancy fell behind that of peer countries. No other advanced economy pivoted quite as sharply to free-market economics as the United States, and none experienced as sharp a reversal in income, mobility, and public-health trends as America did. Today, a child born in Norway or the United Kingdom has a far better chance of outearning their parents than one born in the U.S.

This story has been extensively documented. But a nagging puzzle remains. Why did America abandon the New Deal so decisively? And why did so many voters and politicians embrace the free-market consensus that replaced it?

Since 2016, policy makers, scholars, and journalists have been scrambling to answer those questions as they seek to make sense of the rise of Donald Trump—who declared, in 2015, “The American dream is dead”—and the seething discontent in American life. Three main theories have emerged, each with its own account of how we got here and what it might take to change course. One theory holds that the story is fundamentally about the white backlash to civil-rights legislation. Another pins more blame on the Democratic Party’s cultural elitism. And the third focuses on the role of global crises beyond any political party’s control. Each theory is incomplete on its own. Taken together, they go a long way toward making sense of the political and economic uncertainty we’re living through.

“The American landscape was once graced with resplendent public swimming pools, some big enough to hold thousands of swimmers at a time,” writes Heather McGhee, the former president of the think tank Demos, in her 2021 book, The Sum of Us. In many places, however, the pools were also whites-only. Then came desegregation. Rather than open up the pools to their Black neighbors, white communities decided to simply close them for everyone. For McGhee, that is a microcosm of the changes to America’s political economy over the past half century: White Americans were willing to make their own lives materially worse rather than share public goods with Black Americans.

From the 1930s until the late ’60s, Democrats dominated national politics. They used their power to pass sweeping progressive legislation that transformed the American economy. But their coalition, which included southern Dixiecrats as well as northern liberals, fractured after President Lyndon B. Johnson signed the Civil Rights Act of 1964 and the Voting Rights Act of 1965. Richard Nixon’s “southern strategy” exploited that rift and changed the electoral map. Since then, no Democratic presidential candidate has won a majority of the white vote.

Crucially, the civil-rights revolution also changed white Americans’ economic attitudes. In 1956, 65 percent of white people said they believed the government ought to guarantee a job to anyone who wanted one and to provide a minimum standard of living. By 1964, that number had sunk to 35 percent. Ronald Reagan eventually channeled that backlash into a free-market message by casting high taxes and generous social programs as funneling money from hardworking (white) Americans to undeserving (Black) “welfare queens.” In this telling, which has become popular on the left, Democrats are the tragic heroes. The mid-century economy was built on racial suppression and torn apart by racial progress. Economic inequality was the price liberals paid to do what was right on race.

The New York Times writer David Leonhardt is less inclined to let liberals off the hook. His new book, Ours Was the Shining Future, contends that the fracturing of the New Deal coalition was about more than race. Through the ’50s, the left was rooted in a broad working-class movement focused on material interests. But at the turn of the ’60s, a New Left emerged that was dominated by well-off college students. These activists were less concerned with economic demands than issues like nuclear disarmament, women’s rights, and the war in Vietnam. Their methods were not those of institutional politics but civil disobedience and protest. The rise of the New Left, Leonhardt argues, accelerated the exodus of white working-class voters from the Democratic coalition…

McGhee’s and Leonhardt’s accounts might appear to be in tension, echoing the “race versus class” debate that followed Trump’s victory in 2016. In fact, they’re complementary. As the economist Thomas Piketty has shown, since the’60s, left-leaning parties in most Western countries, not just the U.S., have become dominated by college-educated voters and lost working-class support. But nowhere in Europe was the backlash quite as immediate and intense as it was in the U.S. A major difference, of course, is the country’s unique racial history.

The 1972 election might have fractured the Democratic coalition, but that still doesn’t explain the rise of free-market conservatism. The new Republican majority did not arrive with a radical economic agenda. Nixon combined social conservatism with a version of New Deal economics. His administration increased funding for Social Security and food stamps, raised the capital-gains tax, and created the Environmental Protection Agency. Meanwhile, laissez-faire economics remained unpopular. Polls from the ’70s found that most Republicans believed that taxes and benefits should remain at present levels, and anti-tax ballot initiatives failed in several states by wide margins. Even Reagan largely avoided talking about tax cuts during his failed 1976 presidential campaign. The story of America’s economic pivot still has a missing piece.

According to the economic historian Gary Gerstle’s 2022 book, The Rise and Fall of the Neoliberal Order, that piece is the severe economic crisis of the mid-’70s. The 1973 Arab oil embargo sent inflation spiraling out of control. Not long afterward, the economy plunged into recession. Median family income was significantly lower in 1979 than it had been at the beginning of the decade, adjusting for inflation. “These changing economic circumstances, coming on the heels of the divisions over race and Vietnam, broke apart the New Deal order,” Gerstle writes. (Leonhardt also discusses the economic shocks of the ’70s, but they play a less central role in his analysis.)

Free-market ideas had been circulating among a small cadre of academics and business leaders for decades—most notably the University of Chicago economist Milton Friedman. The ’70s crisis provided a perfect opening to translate them into public policy, and Reagan was the perfect messenger. “Government is not the solution to our problem,” he declared in his 1981 inaugural address. “Government is the problem.”

Part of Reagan’s genius was that the message meant different things to different constituencies. For southern whites, government was forcing school desegregation. For the religious right, government was licensing abortion and preventing prayer in schools. And for working-class voters who bought Reagan’s pitch, a bloated federal government was behind their plummeting economic fortunes…

The top marginal income-tax rate was 70 percent when Reagan took office and 28 percent when he left. Union membership shriveled. Deregulation led to an explosion of the financial sector, and Reagan’s Supreme Court appointments set the stage for decades of consequential pro-business rulings. None of this, Gerstle argues, was preordained. The political tumult of the ’60s helped crack the Democrats’ electoral coalition, but it took the unusual confluence of a major economic crisis and a talented political communicator to create a new consensus. By the ’90s, Democrats had accommodated themselves to the core tenets of the Reagan revolution. President Bill Clinton further deregulated the financial sector, pushed through the North American Free Trade Agreement, and signed a bill designed to “end welfare as we know it.” Echoing Reagan, in his 1996 State of the Union address, Clinton conceded: “The era of big government is over.”

In the remainder of the article, the author says that the nation is at an inflection point, ready for a change. But what that change will be determined by voters next year.
