How well does the Fed protect the purchasing value of the dollar?

”First, it is important to understand the Federal Reserve System.  Some people claim it is a secret cabal of elite bankers, while others claim it is part of the federal government.  In reality it is a bit of both.  The Federal Reserve System is the collusion of big government and big business to profit at the expense of taxpayers.  The Fed’s bailout of large banks during the financial crisis propped up poorly-run corporations that should have gone under, giving them a market-distorting advantage that no business in the United States should receive.  The recent news about JP Morgan is a case in point.  JP Morgan, a recipient of $25 billion in bailout money, recently announced it lost another $2 billion.  If a corporation shows itself to be a bottomless money pit of ‘errors, sloppiness and bad judgment,’ the Fed shouldn’t have expected $25 billion in free money to change that or teach anyone a lesson in fiscal discipline.  But it determined that this form of deliberate capital destruction was preferable to one business suffering bankruptcy.”
