You are wrong. He didn’t just say income disparities are undesirable. He called then “Un-American”.
Income disparities are inevitable in a free economy run by free people. To say income disparities are Un-American is to say a free economy is Un-American.
That makes him one of then ipso facto
Disparities due to socialist policies of increased taxes, regs, and entitlements are very "un-American".
Lack of freedom which causes poverty and keeps the poor down is "un-American". There is little social mobility now...exactly what Bush says here.
I have been saying for years that disparities under Obama are "un-American" and wrong. Go ahead and defend them if you like but it's very telling that you defend the current disparity under Obama IMO.
