90% of Moore's stuff is no more feasible than 90% of the right-wing nut stuff.

Not all of the GOP/conservatism is bad. Making it black/white and about rich vs. poor is a gross oversimplification. It also fails to differentiate between economic and social policies, where many people's views can be diametrically opposed (take for example libertarianism which is socially liberal while economically conservative).

In reality, most analysis shows that a large portion of the electorate falls into a moderate/centrist category. The problem is that both political parties here in the US have become focused on catering to the "core" and then trying to pull a majority of moderates with small concessions as a strategy to win elections. Without any viable third party, both parties work actively to keep it a "good vs. evil" two party system, and voters consistently head to the voting booth trying to select between what they consider the lesser of two evils.

My personal belief is that greed/evil is a universal constant in society and it gravitates towards wherever power lies - basically, the shit rises to the top. Negative maybe, but every instance I've seen of an imbalance between corporate / gov't power results in the general populace being screwed.
