It is interesting that the 'most liberal' states on everyone's lists are expensive and sought after, while the 'most conservative' are generally cheap backwaters. Coincidence? I think not.
while Republican politics is more oriented toward expanding the overall size of the economic pie so that everyone can have a bigger piece.Incorrect, Republicans are for religion and against upper education along with thier permanent hostility to scientific-progress (which is nothing new as we saw with the Catholic Church condeming scientists as heretics) and is thus regressive for the economy.
Why do they do such a thing?
Main explanation could be, as people become more educated, thier less likely to turn to blind faith than logic and people think for themselves, so the "mind-control" aspect of religion gets automatically thrown out the window.
