I would really like for someone to emerge from the Republican Party that has something substantive to contribute to this problem.
They don't consider this a problem, but rather the goal. An desperate and thus obedient and cheap-to-exploit working class is precisely their dream, and they have most definitely achieved it. The GOP is probably the most successful political party in history.
Yup, that's basically true. Republican economics, be it Reaganomics, Ron Paul Gold Buggery, Hayek worship, squealing about the deficit or taker blaming, is not economics, it's agitprop for the masses. If you really want to understand Republicans, read Karl Marx.
