Excellent summary. Might be worth noting that even if a party arose that wanted to make significant economic changes they'd be dealing with US and international finance interests that would make that very difficult, and we are probably stuck in the same political rut that US citizens find themselves: economic and material change is not really on the table for any party. You just get to pick your flavor of social stance and the general economic sector the little money that does come gets directed to (urban/real-estate or rural/oil). We're baked into the international religion of the holy free market, same as everyone else.
