>The task of government was not to stop selfish striving—a hopeless task—but to harness it for the public good [0]

I agree we should not let the rich and powerful corrupt our government. I don't know your mind, but I have heard this argument before, usually by folks who consider such efforts to be government overreach. This also ignores the placement of burden in such a corrupting influence; that it is the fault of government allowing itself to be corrupted, not the "selfish striving" person/business/organization. I guess amoral sociopathic behavior is permitted behind the corporate veil and there is nothing that can or should be done about it.
