i have a challenge for you (and im being sincere).
I would like you to point out how taxes on the highest bracket effect the economy.
I have actually done projects on this topic and i have failed to find a link between taxes, capital gains tax, and corporate tax rates in relation to GDP growth, or private investment (which drives growth), or unemployment (the lagging indicator of growth).
I leveraged non-partisan data like the CBO and the IRS and used data straddling from the great depression to current.
I could not find a statistical link between lowering taxes on the rich and growth or a change in the 1st or 2nd derivative that i could attribute to taxes.
This is using 80 years of data.
