> It’s basically the Laffer curve which argues that tax receipts can actually go down with higher taxes rates as tax’s can discourage growth if high enough.

What you are describing is if we are on the right side of the curve. But is there any evidence that this is true?

When I read Sowell, someone who I imagine would be a champion for this cause, he cites the 1920s as his evidence that trickle-down works which doesn’t inspire confidence. If there is no modern evidence, why are we even entertaining this theory today?
