First, you have to think like a Little Goon. Their thinking consists of stereotypes designed to fit their emotional agenda. That means when they speak of "the wealthy" they automatically assume the wealthholder is a conservative who votes for Republicans. This allows their simplistic nose-length thinking to make sense. It's OK to punish the non-liberals.
Of course, none of their childish thinking is based on reality. The Little Goons' burning desire is to use taxes as a club with which to bash conservatives over the head. In their little beady brains, it will somehow be used to bash only conservatives over the head. Rich democrats and liberals in the Little Goon World need not worry.
The Little Goon lack of understanding of economics is legendary. They have no ability to distinguish between "wealth" and "income". What they really want is seizure of assets belonging to conservatives. They are just too stupid, immature, scatterbrained, and unfocused to be able to verbalize it.
