When economy is good, we can afford to think about trivial things..
I agree with Krugman; &add, we should focus on action items of higher material impact than political aspirations of the right & wrong of which group of individuals should be proportioned a slice.
a) Growth (ie. internet boom '95-'01, security '01-'05, housing boom '03-'07)
b) Stagnation (economic shifting '07-'12)
