It's amazing to me that trickle-down economics is a thing that's taken even remotely seriously. Even more so because the reason this became popularized in the first place was because of Saint Reagan, even though, if you look at the data, 1) his tax cuts never came close to paying for themselves and 2) any economic growth that occurred almost 100% had nothing to do with tax cuts.
On no.1, Reagan's promise on tax cuts increasing revenue failed so badly that he had no choice but to enact massive tax hikes only a year later. On no. 2) the massive growth that Reagan got during his presidency was almost entirely due to the fed lowering interest rates and not his shitty tax cuts. I mean, if you look at the data, the growth/reductions in economic activity coincide nearly perfectly. When Reagan enacted the first round of tax cuts in 1981, for nearly an entirely year, there were still millions of jobs being lost (not saying his tax cuts caused those job losses, but they didn't do shit to stop them either). But when the fed lowered the interest rates in late 1982, growth began almost immediately. So either the tax cuts just needed a year to get into their groove and just coincidentally happened to start working once the fed lowered interest rates, or, and just hear me out, the tax cuts didn't have shit to do with anything!
It's also even more aggravating because Reagan's economic growth wasn't even the best during the time. Jimmy Carter, "history's greatest monster" before Obummer took the mantle, presided over 10 million jobs in 4 years, compared to Reagan's 16 million in 8. And that happened under Carter's way higher 70%+ top tax rates. Then you had Clinton, who also jacked up rates higher than what they were before Reagan left office, which every Republican said would lead to economic destruction, but in fact, led to the greatest job growth period in history.
I mean sure, TDE seems like it's not so far fetched to work if taxes are too high. Indeed, the one time that tax MAY have worked, might have been under Kennedy, where the top tax rate went from 90% to 77%. Sure, one could MAYBE make the case that 90% was indeed too high and was becoming counterproductive. But even if we agree on that, as far as I can tell, it is literally the only time in U.S. history that such a thing worked. Every other time it's been implemented, whether under Reagan, Bush II, Brownback in Kansas, Walker in Wisconsin, Christie in New Jersey, Rick Scott in Florida, Bobby Jindal in Louisiana, whoever the hell runs Oklahoma, and countless other right-wing examples, they have ALL repeatedly LOST revenue, EVERY. SINGLE. TIME.
UGH!
