To me, the lesson is simple. Ideologically driven government = BAD. BAD = more debt.
I agree but IMO it’s even worse than that. Historically representative governments always over extend themselves fiscally in order to buy the happiness or patriotism (votes) of the people in order to get or stay in power. It’s always been that way and always will because it plays to human nature on both sides those in power and those seeking their largess.
Sadly ideologically driven government tends to become driven by the “true-believers” who are often willing to do anything to see their utopian ideals realized.
