Donald Trump’s plan to lower taxes and deregulation, to “incentivise” investors and “free up” the economy won’t work because it never worked in the past.
When Ronald Reagan tried it in the 1980s, he claimed that tax revenues would rise. Instead, growth slowed, tax revenues fell, and workers suffered. The big winners in relative terms were corporations and the rich, who benefited from dramatically reduced tax rates.
Here’s Trump’s dilemma. His tax reform must be revenue neutral. That’s a political imperative: with corporations sitting on trillions of dollars in cash while ordinary Americans are suffering, lowering the average amount of corporate taxation would be unconscionable – and more so if taxes were lowered for the financial sector, which brought on the 2008 crisis and never paid for the economic damage. Moreover, Senate procedures dictate that to enact tax reform with a simple majority, rather than the three-fifths supermajority required to defeat an almost-certain filibuster by opposition Democrats, the reform must be budget-neutral for 10 years.
Most economists would agree that America’s current tax structure is inefficient and unfair. Some firms pay a far higher rate than others. Perhaps innovative firms that create jobs should be rewarded, in part, by a tax break. But the only rhyme or reason to who gets tax breaks appears to be the effectiveness of supplicants’ lobbyists.
But there’s the rub: the money must come from someone’s pocket. Import prices will go up. Consumers of cheap clothing from China will be worse off. To Trump’s team, this is collateral damage, the inevitable price that must be paid to give America’s plutocrats more money. But retailers such as Walmart, not just its customers, are part of the collateral damage, too. Walmart knows this – and won’t let it happen.
A politically astute president who understood deeply the economics and politics of corporate tax reform could conceivably muscle Congress toward a reform package that made sense. Trump is not that leader. If corporate tax reform happens at all, it will be a hodge-podge brokered behind closed doors. More likely is a token across-the-board tax cut: the losers will be future generations, out-lobbied by today’s avaricious moguls, the greediest of whom include those who owe their fortunes to scummy activities, like gambling.
The sordidness of all of this will be sugarcoated with the hoary claim that lower tax rates will spur growth. There is simply no theoretical or empirical basis for this, especially in countries like the US, where most investment (at the margin) is financed by debt and interest is tax deductible. The marginal return and marginal cost are reduced proportionately, leaving investment largely unchanged. In fact, a closer look, taking into account accelerated depreciation and the effects on risk sharing, shows that lowering the tax rate likely reduces investment.
In a country with so many problems – especially inequality – tax cuts for rich corporations will not solve any of them. This is a lesson for all countries contemplating corporate tax breaks – even those without the misfortune of being led by a callow, craven plutocrat.
