buffett is a smart guy... but he may not realize that all the things that have made him rich in the past, are not the same things that will make him rich in the future.
i think he would have to change his whole business model to profit in this new era... and his business is already too huge to make these drastic changes.
i also think he has had some help along the way from very powerful people... and maybe now he will owe them some favors. so his decision to buy GS may not have been in the best interest of his company, but the "higher ups" told him that he had too. and buffett is so filthy rich, that i doesn't really matter to him if his share prices fall. the only way he could have gotten that rich is by playing the game with the powerful people... and now they're forcing him to do this deal.
just a thought, maybe i'm way off base... but buying GS at that share price doesn't seem like a smart business decision to me.
