Given the recent collapse of the global financial market, I am not sure its wise to push the "learn how to invest overnight" business model. I suppose television pitch-men still have to make their living too.
That said, those who decide to try and make "ten, twenty, even sixty thousand dollars month!" purchasing the simple "investment fortune in a box" programs two words spring to mind...caveat emptor.
One silver lining....the mustachiod, flip-flop wearing, yacht captain promising endless returns on real estate appears to have disappeared from the television.
