Welfare states depend on economies of scale that only states can provide. Switching to a culture of totally private mode of investment would mean an end to the welfare state and the slipping of much of the population into precarity.

However, as we have abundantly seen in the Middle East, making life worse for the populace tends to hinder those very moves towards more just government because of the resentment it breeds.
