Transaction consist of market.
These transactions are driven by human nature and they create three main forces that drive the economy. Number one, productivity growth. Number two, the short term debt cycle(5-8年). And number three the long term debt cycle. (75-100年)

Four ways to slove the deleveraging:
cut spending(austerity紧缩–deflation),
reduce debt(default and restructuring),
distribute wealth,
print money.

Three rule of thumb:
1.don’t have debt rise faster than income because your debt burdens will eventually crush you.
2.don’t have income rise faster than productivity because you’ll eventually become uncompetitive.
3.do all that you can to raise your productivity because in the long run, that’s what matters most!!!
