While I generally applaud your reasoning it doesn't go to the full depth of our social issues and explain why each generation produces more idiots. It misses the economic factors that are the main motivators of life in our country.

As people are forced into the reality of living on the edge of financial ruin for the smallest mistake in their lives they become hostile toward their society. They don't trust each other or the foundations of a society that is always ready to throw them under the bus if they step off the hamster wheel for even a moment. The stakes for doing so are too high, but they aren't able to express or act on any change in the fundamental structure of the economy out of fear that the alternative may be worse yet.

If your view, which is difficult to argue with in the big picture, is that the underlying structures of the society are against you but don't understand them sufficiently to affect change, it would be expected that you might resist further intrusion or control from the society that sees you as dispensible unless you keep the wheel in motion.
