mthead....I was just looking at the charts you posted....it's a bit difficult to read the years and some of the writing on the side....but, just looking at the trend lines..........
I REALLY HOPE YOU ARE KIDDING !!!!!!
take another look........
what are you looking for a linear relationship....????
consider all the charts...the overall trend appears similar...
they clearly show that once the tax rate is dropped to a certain level, the positive results follow....when the tax rate is dropped minimally, yet still remains high, nothing changes....these charts show that the tax rate has to be close to 40% to see things happen.....or, is it my eyeballs and I can't see the chart?
look at the last approx. 25+ years........especially, for the first (top) chart......look at the upward spike....I think it's 1980 or 82.....and, the rest follow suit....BIG IMPROVEMENT.....lower taxes...get results.....
you can spin it....but, unless it's my eyes....those charts show that lowering taxes yields positive results....
