What answer would that be? Because looking here[1], the effective tax rate during our largest job growth (Clinton Administration) was also when we saw the largest effective tax rates for the 10, 5, and 1%.
I guess I have to correlate until we run out of data, then checkmate or something.
this debate is so complicated that you can easily take data to support any side of the argument
for eg. the effective rates don't match up for the 80s but they do for the 90s. they also don't take into account capital gains, which is what most of the top 5, 1% etc. pay
then if I was arguing the other side of the debat I would say that this data hasn't been normalized for purchasing power
