headline economic figures have become less and less of a useful guide to how actual families are doing—something repeatedly noted by Democrats during the Obama recovery and the Trump years. Inequality may be declining, but it still skews GDP and income figures, with most gains going to the few, not the many. The obscene cost of health care saps family incomes and government coffers without making anyone feel healthier or wealthier.

To be clear, the headline economic numbers are strong. The gains are real. The reduction in inequality is tremendous, the pickup in wage growth astonishing, particularly if you anchor your expectations to the Barack Obama years, as many Biden staffers do.

During the Biden-Harris years, more granular data pointed to considerable strain. Real median household income fell relative to its pre-COVID peak. The poverty rate ticked up, as did the jobless rate. The number of Americans spending more than 30 percent of their income on rent climbed. The delinquency rate on credit cards surged, as did the share of families struggling to afford enough nutritious food, as did the rate of homelessness.

the White House never passed the permanent care-economy measures it had considered.

the biggest problem, one that voters talked about at any given opportunity, was the unaffordability of American life. The giant run-up in inflation during the Biden administration made everything feel expensive, and the sudden jump in the cost of small-ticket, common purchases (such as fast food and groceries) highlighted how bad the country’s long-standing large-ticket, sticky costs (health care, child care, and housing) had gotten. The cost-of-living crisis became the defining issue of the campaign, and one where the incumbent Democrats’ messaging felt false and weak.

Rather than acknowledging the pain and the trade-offs and the complexity—and rather than running a candidate who could have criticized Biden’s economic plans—Democrats dissembled. They noted that inflation was a global phenomenon, as if that mattered to moms in Ohio and machinists in the Central Valley. They pushed the headline numbers. They insisted that working-class voters were better off, and ran on the threat Trump posed to democracy and rights. But were working-class voters really better off? Why wasn’t anyone listening when they said they weren’t?

Voters do seem to be less likely to vote in their economic self-interest these days, and more likely to vote for a culturally compelling candidate. As my colleague Rogé Karma notes, lower-income white voters are flipping from the Democratic Party to the Republican Party on the basis of identitarian issues. The sharp movement of union voters to Trump seems to confirm the trend. At the same time, high-income voters are becoming bluer in order to vote their cosmopolitan values.

The Biden-Harris administration did make a difference in concrete, specific ways: It failed to address the cost-of-living catastrophe and had little to show for its infrastructure laws, even if it found a lot to talk about. And it dismissed voters who said they hated the pain they felt every time they had to open their wallet.

Since 1949, job growth under Democratic presidencies has been more than twice as large as that during Republican administrations (2.47% to 1.07%). Excluding public sector jobs, the advantage is even greater (2.55% to 0.97%). Other key averages reveal a similar distinction during this period: Real business investment growth advanced 6.58% under Democratic presidents and 2.98% under their Republican counterparts; real personal income — excluding government transfers — increased 2.66% and real economic growth per capita (net domestic product) advanced 2.6% under Democratic chief executives, but only by 1.41% and 1.28%, respectively, under Republican leaders. Inflation has also been much more modest under Democratic presidents (2.91% compared to 3.28% under their Republican counterparts), with an even more decided advantage when volatile energy and food markets are excluded (2.87% compared to 3.59%).

Of the 11 U.S. recessions we’ve endured over the past 75 years, 10 began in Republican presidential administrations; only Jimmy Carter — embracing Republican-style fiscal, monetary and regulatory policy much more completely than any other recent Democratic president — presided over a “Democratic” recession. The two “double-dip” recessions of 1980 and 1981-82, straddling the late Carter and early Reagan administrations, are almost indistinguishable in their policy origins.

We are reminded consistently by pundits, journalists and scholars that tax cuts represent what may be our most readily available and useful tool for economic stimulus. Flat, or flatter, taxes, we are told, are the only means to the achievement of tax simplicity and tax compliance.

Even on the question of who tends to favor lower or higher taxes, it is easy to be deceived. When income taxes are reduced (at the federal and state level) and the entire tax code is rendered less progressive as a result, two things happen almost automatically: other much more regressive taxes rise to fill the vacuum created by universally demanded (if not readily acknowledged) public services and consumer demand falters as higher taxes begin to fall on those compelled to spend all that they earn. Overall economic activity and prospective revenue growth, in turn, begin to stagnate, triggering a vicious cycle of tax rate increases (among the untouched regressive tax vehicles), just to maintain public services and economic activity.

Republican politicians have stumbled upon a remarkably effective political strategy: preach tax cuts as the be-all and end-all of successful economic policy; ignore the ways in which federal income tax cuts often lead to increased tolls, fees and property, sales, and excise tax increases; relinquish all but rhetorical opposition to the federal deficits created by federal tax cuts; and cap it off by hinting repeatedly that more could be done — allegedly to great effect — by reducing government spending directed at “undeserving” and “unambitious” poor people of color.

Republican political leaders have their cake and eat it too, riding a diffuse anti-tax sentiment to political victory. Actual results in this game don’t often matter, at least as long as their Democratic opponents succeed in staving off the most precipitous decline with safety nets and the preservation of some progressive fiscal policy elements.

Begun quietly with what Republican activist and Wall Street Journal editor Jude Wanniski called the “Two Santa Claus Theory” — under which Republicans could counter the Democratic social spending Santa Claus with their own tax-cutting Kris Kringle — this approach promised political “success” even amid policy failure, for opponents could be pinned with the deficits and damage it produced.

Exploiting normal psychological tendencies to imagine that “more money in my pocket” and “less money in theirs” simply must be good policy, the widespread ignorance of actual public spending and significant intergovernmental fiscal policies (where federal change forces state and local change, or vice versa), and the compelling notion that personal economic opportunity or success must be derived from personal talent and initiative (rather than significant public policy reform), the “Two Santa Claus” strategy has buoyed a Republican Party that has consistently delivered sub-par results.

Why costs are so high: The simplest answer is that schools have had little incentive to control costs, particularly when abundant student loans — both public and private — can make tuition rates appear more affordable than they really are.Moreover, some schools are motivated to spend on high-ticket items like new construction, because that can attract wealthier students (including from overseas) who don't request financial aid. In the end, however, those costs often get passed down to everyone.This is a systemic issue, which explains why most politicians have preferred to play along the easier margins.

There are possible solutions that have been circulating among education experts, not all of which rely on taxpayer largesse like making public college free for lower-income students.One would be to limit loans tied to education at schools that have a demonstrated history of onerous student debt burdens. In other words, if most of a school's students aren't receiving the sort of education that allows them to pay off their loans, cut it off at the source.This could include a gainful employment rule focused on career programs, which is favored by the Biden administration but languishing in Congress.Another would be to deny federal research grants to schools whose tuition rates increase at an unacceptably high level. This would be particularly impactful at large public and private universities.The federal government also could consider revoking the tax-exempt status of schools that exceed tuition inflation limits, although that likely would face court challenges.
