They are thinking short term. They want the biggest profit now so that is usually their best asset. But if they hold on to those and get rid of the bad ones, they will make more money in the future. Not many CEOs have long term strategy in mind or their "long term" is only 3-6 months out. They just want to make the quick buck by showing growth NOW. Get that big bonus and then worry about the company's future later. Companies with CEOs that got paid tons of money (and huge bonuses) while their company tanked: K-mart (got bought out by Sears). Home Depot Disney Dell and now Exxon. (soon to be...Citi's Chuck Prince) All these guys got kicked out at the end (except for Exxon). But they made huge amounts of money. What do they care. Talk about greed!
