Why do Republican politicians support tax cuts for the wealthy despite their unpopularity (as documented in a part I left out), and their failure to spur economic growth?:
Voodoo Never Dies, by Paul Krugman, Commentary, NY Times: So Donald Trump has unveiled his tax plan. It would, it turns out, lavish huge cuts on the wealthy while blowing up the deficit.
This is in contrast to Jeb Bush’s plan, which would lavish huge cuts on the wealthy while blowing up the deficit, and Marco Rubio’s plan, which would lavish huge cuts on the wealthy while blowing up the deficit.
For what it’s worth, it looks as if Trump’s plan would make an even bigger hole in the budget than Jeb’s. Jeb justifies his plan by claiming that it would double America’s rate of growth; The Donald, ahem, trumps this by claiming that he would triple the rate of growth. But really, why sweat the details? It’s all voodoo. The interesting question is why every Republican candidate feels compelled to go down this path.
You might think that there was a defensible economic case for the obsession with cutting taxes on the rich. That is, you might think that if you’d spent the past 20 years in a cave (or a conservative think tank). ...
True, you can find self-proclaimed economic experts claiming to find overall evidence that low tax rates spur economic growth, but such experts invariably turn out to be on the payroll of right-wing pressure groups (and have an interesting habit of getting their numbers wrong)... There is no serious economic case for the tax-cut obsession.
Still,... every Republican who would be president is committed to a policy that is both demonstrably bad economics and deeply unpopular. What’s going on?
Well,..., it’s straightforward and quite stark: Republicans support big tax cuts for the wealthy because that’s what wealthy donors want. No doubt most of those donors have managed to convince themselves that what’s good for them is good for America. But at root it’s about rich people supporting politicians who will make them richer. Everything else is just rationalization.
Of course, once the Republicans settle on a nominee, an army of hired guns will be mobilized to obscure this stark truth. We’ll see claims that it’s really a middle-class tax cut, that it will too do great things for economic growth, and look over there — emails! And given the conventions of he-said-she-said journalism, this campaign of obfuscation may work.
But never forget that what it’s really about is top-down class warfare. That may sound simplistic, but it’s the way the world works.
