Why is the economy still a debacle?

As you know, the U.S. economy has been in bad shape for a while now, and the government just issued a $700 billion bailout to fix the mess.  But I’m hearing in the news that things are still bad on the economic front.  I don’t understand…

I realize these corporations are huge and complicated, but how long should it take to feel the effects of billions of dollars?  I can envision it helping really quick.  (Just imagine if you were given a billion dollars, how long it would take to fix your economic problems.)

The government gave these billions of dollars to the financial experts, the people who have been in the industry for years, the people who run the critical companies — the mortgage lenders, the big banks, the insurers, the credit card issuers, etc.  These are the people who have the authority in their companies to make the difficult decisions, to make a difference.  These people are paid big bucks to know what they’re doing.  These people are… um… the people who… uhh… got us into this mess in the first place…  OH, NO!  WHAT HAVE WE DONE???
