Obviously you haven't been hanging around many career politicians or corporate executives.

The problem isn't that older people don't care, it's that the older people in charge don't care.

Maybe they do in fact care, but from the kinds of decisions they make it certainly does not appear that they do.

You can care about other people, but there's nothing like experiencing a problem first-hand. It's a level of selflessness that most people don't ever realize, because it goes against human nature. If a flight loses cabin pressure, you need to put on your own oxygen mask before someone else's. Not that you don't care for other people, but if you don't care for yourself first, you will literally be unable to help others.
