Should we nationalize our banks?

According to Dilbert, the comic strip, companies are run for the benefit of the shareholders, not the employees.  In that vein, it would seem that banks are run for the benefit of their shareholders, not the general public.   Those who oppose nationalizing our failed banking system argue that nationalization would wipe out their investments.  These are the same shareholders who sat by idly while the senior executives ran banks into the ground.  Should we really care if they lose their money?  Many of our fellow citizens are unemployed or going without pay raises because of our current economy - do they care if the investor class loses a few million? Our current mess is due in no small part to the deregulation of the banking industry.  Capitalism and the free market helped make America the nation it is today, however, letting banks operate without government oversight is like giving whisky, money, and car keys to teenage boys. 

Maybe it's time we looked into nationalizing our banks.
