Tax cuts for the wealthy have long drawn support from conservative lawmakers and economists who argue that such measures will “trickle down” and eventually boost jobs and incomes for everyone else. But a new study from the London School of Economics says 50 years of such tax cuts have only helped one group — the rich.
The new paper, by David Hope of the London School of Economics and Julian Limberg of King’s College London, examines 18 developed countries — from Australia to the United States — over a 50-year period from 1965 to 2015. The study compared countries that passed tax cuts in a specific year, such as the U.S. in 1982 when President Ronald Reagan slashed taxes on the wealthy, with those that didn’t, and then examined their economic outcomes.
Per capita gross domestic product and unemployment rates were nearly identical after five years in countries that slashed taxes on the rich and in those that didn’t, the study found.
But the analysis discovered one major change: The incomes of the rich grew much faster in countries where tax rates were lowered. Instead of trickling down to the middle class, tax cuts for the rich may not accomplish much more than help the rich keep more of their riches and exacerbate income inequality, the research indicates.
“Based on our research, we would argue that the economic rationale for keeping taxes on the rich low is weak,”Julian Limberg, a co-author of the study and a lecturer in public policy at King’s College London, said in an email to CBS MoneyWatch. “In fact, if we look back into history, the period with the highest taxes on the rich – the postwar period – was also a period with high economic growth and low unemployment.”
Because the analysis ends in 2015, the research doesn’t include President Donald Trump’s massive tax overhaul, which he signed into law in late 2017 and which slashed taxes for the rich and corporations while providing a moderate cut for the middle class. But Limberg, who co-authored the study with David Hope, a visiting fellow at the London School of Economics’ International Inequalities Institute, said that he wouldn’t expect the results of that tax cut to be much different.
Already, Mr. Trump’s tax cuts have lifted the fortunes of the ultra-rich, according to 2019 research from two prominent economists, Emmanuel Saez and Gabriel Zucman of the University of California at Berkeley. For the first time in a century, the 400 richest American families paid lower taxes in 2018 than people in the middle class, the economists found.
The “careful” new research from the London School Economics “suggests indeed that tax increases on the wealthy should be considered post-COVID,”…
