I don’t know for sure but it could be the people may not understand the real root cause and just lashing out. We see that in this country sometimes - ignorant populism.
That is exactly it in my opinion. The vast majority of people are now economic and fiscal illiterates thanks to the left-wing government schools that prevail in most western nations. Most people have no clue where money comes from and expect that the government can simply make more without consequences. It seems that the current crises are going to be the mechanism for giving people this education.
People incapable of learning from the past due to an incompetent educational system and an irresponsible fourth estate are going to insist on stretching the status quo until local disasters finally become inevitable, viz. Greece. With some luck the less screwed-up countries then have enough time margin remaining to take corrective political action (i.e. throw the left-wing morons out of office) and fix the structural imbalances before it takes them down as well. The sheer size of the US economy and the grass-roots awakening give me hope that the US will actually come through this better that most of the western world.
