Exactly right. Revanchist politics lead to boom/bust debt cycles in government. One party spends way too much and hurts the citizens, the other party uses their mandate to fix the overspending as a pretext to subvert government controls and agencies, and slash and burn in a way that hurts citizens. And 95% of the population blindly, religiously even, suport this and yet don't feel at all responsible for the current state of affairs. "They did it!" seems like the new American ethos.
