Don't be fooled by the Obama bounce. There is another wack of sub-prime mortgages due this spring. There has to be a consequnces to printing all this confetti to save financial institutions and finance two wars. Likely it will be massive inflation.
For large-scale infrastructure projects, the money have to come from somewhere to do this. If you can't recycle what you don't have, then you have to raise taxes and up goes inflation.
