Looks like China and the rest of the world refusing to invest in US debt is having an effect, when the USG can’t just print up a whole bunch of QE to spend on hurricane victims.
It's never worked that way.
QE can "fix" the US economy by injecting money into the top most 1%, but if you tried to distribute the QE money more evenly, it would create uncontrollable inflation.
When a net worth 100 000 $ guy gets another 100 000 $, that's life changing. When a net worth 1 billion $ guy gets 10 million $, it most likely doesn't even affect his spending habits or his market impact at all. The money just sits in a bank or stocks, accruing interest without being used to consume and develop real life products (or at most having a slight effect on company investors, but more investment =/= necessarily better, as investors can be wrong about which development direction companies should take).
That's why QE never helped to elevate US living standards or achieve increased national development. National development is correlated with gdp growth, but it is not the same metric.
