The main reason cause this is Chinna gov spent the future expenses on now, and this is not a good idea for a country like China. But China took this responsbility because 2008 and now this big guy can't hold anymore longer. Evidence is the price of staple commodity, espicially the material for industry.Also these cause the junk bouns market becoming like a shit, and many many company are going broke.
Also, the technicial is also a problem cause this happen, the technology make our company got a lower expenses, but this will cause a rat race, who will be going down first will be the problem, and the chain reaction will cause the market going like 1930s
Talked about the 1930s , the situation for this is similar, and finialy they need a war to distory everything, then rebuild, becuase there isn't any player can hold the economy of this world now, 2008 is lucky because CHY wanna to beat USD, they got a big plan for this, and in 5 years, CHY will instead of USD to be the order of the world currency.
So there isnt any good news for the world, why market keep going up?
DOW index will going back to 6000! next year!
Personal thinking, but could be the truth.
