Accept the fact that you've been manipulated all these years...
Yes we see how the tax cuts grew the economy last time and how trickle down failed to ever trickle.
Why select as your data point years when the US economy is suffering from a huge Democrat-provenance recession?
Let's take a look at the historic results of 'trickle-down:"
1. And the tax cuts of the Economic Recovery Act of 1981 stimulated economic growth. “As a 1982 JEC study pointed out,[1] similar across-the-board tax cuts had been implemented in the 1920s as the Mellon tax cuts, and in the 1960s as the Kennedy tax cuts. In both cases the reduction of high marginal tax rates actually increased tax payments by "the rich," also increasing their share of total individual income taxes paid.”
