taxes are regressive. Without exception. If you dont think so, read analysis of them. I posted examples above, naturally they were ignored. I in fact made my case that the actual tax burden is higher on lower income groups, the statements that this was not the case (that upper income groups paid a disreportinante amount of taxes) was made by conservative posters.

As for what national conservatives focus on in terms of taxes, read Heritage or Cato, or Commentary or listen to conservative speakers. I do all the time and they virtually never talk about regressive taxes like sales taxes. Indeed they have championed a national consumption (sales) tax which would be regressive to replace the progressive income tax. Look it up.

The Bush tax cuts focused most gains in upper income groups. Again I cited the evidence for this, and the CBO has come to the same conclusion. The tax cuts were in areas like estate, dividend and capital gains taxes, and the like which are paid primarily by upper income groups. The taxes for lower and lower middle income groups were very small.

Who here thinks its a concidence that conservatives want to replace the progressive income tax with a national sales tax or that Bush cut capital gains, dividence and estate taxes but did zilch about raising the standard deduction

As for whether I proved my case, the data is in the links I presented. Ignoring it does not mean its not there.
