Inflation will indeed be a big problem (for US) down the road, but we'll probably have plenty of time to head it off; Europe is doing really bad on one hand, yet really good in others despite the immense amount of bailout and inflationary pressure it's facing, but it's hard to get a clear assessment of that situation (tho the Irish, Greeks, and Spanish are all on Defcom 1 pretty much economically right now).
But back to this quantitative easing: Since the wake of quantitative easing 1, 17-year U.S. treasury bonds are down 3 basis points while 7-year treasury bonds are UP about 17 points. Too many short term investors right now, trying to make a quick buck off the market and QE. But that's what happens when you live in a world with supercomputers hedging against the market's every move, opposed to honest, genuine old-fashioned investing.
Has anyone seen the second Wall Street film? I haven't, but the one thing on Wall Street that has changed more than anything in the 20+ years since the first film is the New York stock exchange trading floor -- in that it doesn't really exist anymore. I mean, it does, there are still traders and brokers there, but nothing like it was in the 80's. It's all digitized with investment decisions based on computerized data of past and future market movements and fluctuations.
