The endgame of the mixed economy is always going to be a "merged" economy--not being able to tell the men and pigs apart anymore.

Even communist countries have fat cats. They're just loyal Party members, lobbying from the inside out instead of the outside in.

I understand your particular views on corporations and government, at least to the point where you'd think Bernie Sanders is a good idea, but nobody's going to fix anything by giving the government even more power and wealth than it already has, or pretending that powerful political leaders and parties are always going to be more benign than powerful business interests. "Accountability" is a feature of a decentralized, less-powerful, bottom-up government with checks and balances, not the monolith we're developing into.

Where the hell is the Antitrust Act for political entities?

Hillary or Sanders will just make it worse, and I doubt any of the Republicans would make it better.
