Because new necessary skills come along all the time. If you can't drive a car today, for example, you're severely disadvantaged. Or the ability to type more than 20 wpm, or coordinate your thumbs with what a character/cursor does on a screen, or comprehend cause-and-effect once you throw computers and the Internet into the mix.
In another couple of decades there'll be a new skill that everyone has to learn, or else resign to flipping burgers. I, for one, am looking forward to it.
Not the burger flipping part, tho.
