I see a somewhat different split:
(1) Those who worship money above all else, and who therefore believe society is obligated to protect corporate profits first and foremost
(2) Those who have more people-focused values, who recognize that a healthy, truly prosperous society needs to balance the lust for gold against the welfare of the people
In my opinion, that's what the modern GOP has abandoned. The Republicans used to be the responsible grown-ups who understood that businesses existed to make money, but that they also had a responsibility to their communities and their country. America grew and prospered. Those traditional values seemed to have disappeared with the Reagan greed is good era, appealing to the greedy by promising one unfunded tax cut after another. Couple that with anti-abortion pandering to evangelicals and a certain southern demographic, and today's GOP built themselves a substantial fervent, self-serving base. Great for the party; bad for America.
Yes, Democrats have their own problems. Most of their politicians are just as corrupt, and just as self-serving as the right's. And yes, the Dems pay more lip service to the middle class than they do actually serving their interests. Both parties have put America into a death spiral, with a declining middle class and ever-increasing concentration of wealth in the hands of an elite few. America desperately needs a party that actually cares about We, the People, but that's a pipe dream in our system so thoroughly corrupted with money. Until then, unfortunately, our best hope is enough of a public uprising to cow Democratic representatives into covering their asses with a few more crumbs for the working class. It's a damn sure bet Republicans aren't going to help.
