There is something to this. A lot of it has to do with what Americans value. Americans value individuality, expression, personality, ambition, and entrepreneurship. Intelligence is rewarded, of course, but it's not a goal in itself. It's more like a medium for achieving something. That's why there's an old adage in the US that goes, "If you're so smart, how come you ain't rich?". In former Communist countries where individuality, expression, personality, and entrepreneurship were suppressed, intelligence was the goal in itself. Just BECOME smart. If you're not smart, YOU HAVE NOTHING. Because they didn't have anything. In the US, being smart for the sake of being smart is not really a societal value. It's more about what you can do with that intelligence. I bet in Poland there's a bunch of experts on certain matters of the world in occupations that don't require any of that. In the US, it's kind of like, if you're not smart, you can still reach your goals. If you don't know about the Titanic, you can still be creative, expressive, individualistic. You can still find love. You can still be HAPPY.
