You people really frustrate me because you consistently refuse to look at the bigger (global) picture. If anything, it is a miracle that the economy has grew at all last year. Just look at what happened in 2011:
Arab spring produced fears of an oil supply shortage.
Japanese tsunami and earthquake cut off global supply chains and severely damaged the world's third largest national economy.
The US government proved that it is incapable of operating properly, created a crisis out of nowhere, and nearly threw itself into default.
The Eurozone struggled to deal with a real sovereign debt crisis with the constant threat that a chaotic Greek default could tear apart the content, end the Euro, and plunge Europe and all its trading partners into a deep recession.
China and other emerging markets appeared to have overheated economies and appeared to be heading towards a hard landing.
The US housing market has continued to be miserable (housing prices are sticky, remember?).
Weather in the first part of the year was erratic, causing people to miss work, pay higher prices for heating oil, and delays in construction.
Governments were forced to slash worker payrolls as stimulus money ran out.
Banks had to deal with scandals, public backlash, regulations, reduced profits, and had to lay off more people as a result.
So, if you ran a business and read all this going on in the news everyday, what would your project your profits to be in the near future? Would you find this information encouraging enough to invest and hire more workers?
A final point: the Fed can't create inflation if banks don't lend out the money that it is giving them. If the Fed and Mint printed $100 trillion and then dropped it into the Marianas trench, would there be any inflation in the dollar? No, of course not, because it is not "in" the economy. Banks haven't been lending money out because the future has looked so uncertain and bleak for so long that they would have to be stupid to do so.
