What concerns me greatly about US fiscal policy (if one, in fact, characterize what the Fed is doing can as a "policy", and not an horrendous "Hail Mary" pass which absolutely will not benefit American consumers in the slightest) is the reality that trade/financial wars are often followed by real wars.
Historically, the US has generally gotten out of its depressions by going to war. Looking at the evolution of ever more lethal means to inflict injury or death the US has come up with since World War II, that's enough to bring a collective shudder to every thinking person on this planet.See: "You should go kill them for us. Mr. President, I mean, Mr. Vice-President, or we'll have to ... I mean, 'Al Qaeda' will have to blow up another building!"
