A vast superficial knowledge, along with a good memory, the ability of making meaningful connections between far away domains is a scarcely distributed skillset and a quite valuable one in today's Western world.
I'd like to believe this were true. Personally I've found it very difficult to find paid work that allows me to exercise even a fraction of my general knowledge. My best results so far have been with underfunded startups who are trying to do too much with too little - they need people who can tackle a different challenge every week, because they can't afford to hire specialists. But it's not a spectacular way to build a career.
Of course there are other kinds of value than monetary.
