We don't need their money -- the Fed's keep printing up all they want.
How this works is beyond me. I'd have figured that our US dollar would have been rivaling the worth of the Mark of the 1920s Wehrmacht Republic by now -- but apparently our dollar, and printing presses, defy gravity.
China’s sales will not have any effect: the Fed will buy their T-bills if needed to keep interest rates low. The excess liquidity goes into the equity markets here and in China plumping the big banks’ bottom line. So there is massive inflation- in equities, here, in China and Europe, but as the liquidity does not translate into increased demand for consumer or industrial goods. there’s no Weimar style inflation.
