re: Doubt Your Facts As Well
You can find a more detailed treatment of the Reagan economy here.
You can microanalyze economic effects, or you can come down to a simple choice: Is it better for the economy to have the wealth in the private sector, or in the public sector?
Keep in mind when you ask a politician this question, that he may not be entirely unbiased in the matter. I do know that higher taxes have never made a nation more prosperous.
