Trying to make themselves younger?
Really? First of all, it's their (now) geezers who made them great, so the idea of "becoming younger" doesn't really make a lot of sense. Secondly, it's not really about age per se; it's all about MONEY.
Generally, older employees get paid more than younger ones. So, if you're one of the typical stupid, greedy, wildly overpaid and short-sighted asshats who seem to be in charge of most big big corporations these days (and get paid millions for plowing it under thanks to golden parachutes), you fire all your older, more experienced workers -- the guys who made the company great in the first place -- and hire a bunch of "yow'uns" you can pay more cheaply. Or, better yet, you can outsource everything to some third world country! Cut costs, push up that share price (for now), and, in the long term, cut your throat.
Either way, you rid your company of the people who made it great in the first place. So what happens next? You enter what's called a slow death spiral. And join many other once excellent companies who are fading away today after following the same strategy. I'm sure all El Reg readers can come up with a list of members of this fraternity.
