A certain combination of liberal and conservative politics can be detrimental, I'd guess. Conservatives are usually the ones that push for tax cuts. Quite a few liberal minded people are prosperous also, but they tend to be okay with the taxes and the social safety net. One can still be prosperous and generous.
Problem is the conservatives tip the scale toward more cuts and a less compassionate society. The electorate is pretty much split 50 50.
I think if it leaned more toward liberal politics, there would be more compassionate prosperity.
