The biggest problem in the US economy is the balance of trade. That is, there is not balance of trade. Asian countries have too low cost of labor and will continue to have. Therefore, US industry can not compete. Eventually we will all be pressing each others pants.
When did this all change? 1960s was the cross over point. The departure from the good old USA to the new USA. The 1990s is when this problem of the trade deficit accelerated.
Now the economy is going for long term slow growth and perhaps a relative decline in the standard of living.
Any solutions? Well a weaker US dollar should in theory correct this all. However, it has not.
