While government in moderation is a very good thing, more is not better. The benefit curve forms an arc. We are clearly on the downward slope right now. The source of much conflict is that people living in high density communes called cities need more government while people living in America need less. Leftists believe one size fits all for government intrusion and centralized planning, but that is clearly not the case.
At some point on that arc, career Executive Branch employees reach sufficient numbers that their collective clout can protect them from attempts by Congress, the courts or the president to force reform. In the case of Obama the bureaucracies—whose ranks are filled with activist Democrats—have an ally bent on expanding government. The chief aim of ObamaCare, Dodd-Franks, Cap-and-Trade and much of the “Stimulus” is to create new bureaucracies staffed by card-carrying Democrats.
