Saw an interesting guy on Moyer's this last week. John Bogle, who obviously believes in capitalism, was talking about all the money managers (e.g., hedge fund managers) who take but do not add anything of value to the enterprise (corporation and its stockholders). He talked about them taking short term profits to the detriment of long-term value (I guess that's an old theme).
Anyway, his critique reminded me of the sub-prime lenders and all their backing capital and their practices.
Here's Bogle's book. I haven't read it so can't endorse it.
