原來經(jīng)濟周期是這樣理解的： 通過credit 人們支出＞收入，借錢消費，經(jīng)濟蓬勃發(fā)展，但是支出大于生產(chǎn)力 最終會回來，支出＜收入，還債，經(jīng)濟衰退，來彌補之前的過度消費 結(jié)合短期債務(wù)模型?長期債務(wù)模型?生產(chǎn)率增長軌跡 三個建議 1.do not have debt rise faster than income. 2.do no have income rise faster than your productivity 3.do all that you can to raise your productivity 值得反復(fù)觀看
