Those that don't, die. Since companies can die, they can't afford to let waste occur except when times are good. that's what the executives have the huge expense accounts(heck, when times are good, even a lot of sales people get lavish expense accounts), and everyone seems to be getting bonuses. I've worked for growing companies flush with cash, and lean companies just trying to stay afloat. Since the government is always flush with cash, or can at least borrow if they aren't, they never really root out waste.
