With the start of the recent wars and two tax cuts, huge for the wealthy who invested in the wars and reaped more wealth, China was and still is the main supplier of the borrowed funds, the Veterans Administration still grossly under funded budget is mostly borrowed, none paid back for the wars and especially as to the results of those wars, DeJa-Vu all over again:
With $1.28 trillion in U.S. Treasuries, China is easily the biggest foreign holder of American debt.
China has also funneled billions of dollars into private American investments – to the tune of an estimated $54 billion in 2012 alone.
That's our money they've been investing in those American investments!!
