Unfortunately, the folks who become millionaires are usually so single-minded about whatever they are doing that after making their pile they suddenly wake up and realize that they didn't pay any attention to art, literature, or music while they were coming along.
At that point, if they're canny, they hire a gentlewoman or gentleman in distressed circumstances to bring them up to speed. If they're not, they pay thousands of dollars for bad flea market kitsch and learn art appreciation the hard way . . . when their art depreciates . . .
I have a son who's that way. He's so single-minded about what he likes (tinkering with machines and electronics) that any information about art and music goes in one ear and out the other. We keep on providing the information in the hopes that some of it will stick, subconsciously or something.
I hear you. Things are different in more traditional Western societies. This is perhaps due to their well established class structure. Compare, off the top of my head, Elvis Presley or Michael Jackson (collectors of flea market kitsch), to somebody like Pete Townsend or Mick Jagger, or Sophia Loren, who all, in one word, aspired, when it came to cultural values. Elvis only aspired to unlimited quantities of MacBurgers and doughnuts. I see this as a tragedy of American success.
