Lowering the top marginal rates brought in significantly increased tax revenue under Reagan. The term "trickle down" was coined by detractors of supply side economics, and is a buzz word used by leftists. Your bias is showing. I see you don't refer to JFK's fiscal policy in the same terms, yet he also supported lowering the top marginal rates.
I don't know if you're unaware or just biased, but congress controls spending. During the Regan years, congress outspent the windfall tax revenue by approximately two-to-one. It's impossible to spend your way out of debt.
And adding "jmo" is not an effective insulator against criticism when saying something ridiculous.
So if Congress was pumping all the money into the economy--even more than the tax cuts--why can't you see through your bias that it was that that increased revenue taken in? Tax revenue increase because of public investment
It was mainly due our manufacturing capabilities escaped unscathed from WWII we became the world's major producer of many products. Add to that the returning service men and women along with the euphoria of the depression and the war finally behind us. Mickey Mouse could have been President and the country would have boomed.
Living through an era doesn't mean you understand anything about it.
Oh? Nothing to do with the biggest public works project in American history?? I'm sure our economy would have been great without a friggin highway system duh!
