Ask an economist? You're the one who supports these policies, you should, at the very least, be capable of understanding the subject matter and offering some rational defense of your position. Perhaps that is too much to expect...
So you have absolutely no explanation for how raising tax rates had the exact opposite effect that you claim they should have... Fine. You have claimed in the past that it was "simple math", that it really was as simple as "do x y will happen", that by just raising tax rates we could increase tax revenue and that anybody who claimed otherwise didn't understand "simple math", yet here we are with a real life example of your policy completely backfiring, despite what "simple math" had to say.
If you have any intellectual curiosity, you would want to find out for yourself why a policy you support has failed.
If you have any intellectual honesty, you will consider the possibility that what you believe about taxation, is wrong.
