The Fallacy of the Leftist and the Libertarian

 It seems to me that leftists and libertarians both operate from wrong assumptions.

The leftist assumes that the totality of wealth is a big cake that's just there and can be divided up by government. (This isn't literally what they believe, but it's pretty much this.)

The libertarian, for his part, has the opposite belief (again, not literally, but pretty much): that all the wealth in society is created by individuals from their own efforts, ignoring how much everybody owes to infrastructure, civil peace, natural environment, the virtues that have been inculcated by churches and traditional families, and so on. (When I said this on Facebook, once, I was accused of echoing Obama's slogan that "You didn't build that". Well, I think he was right about that much.)
