Wait, what? I mean, I guess that just watching your parents work doesn’t “prepare” you for work any more than watching TV does, but that’s because it’s completely unrelated. Watching your parents go to high-powered executive jobs doesn’t “prepare” you for work in the 21st century either, education does. My father was a police officer (they don’t make much money) and my mother stayed home with us - they both encouraged us to study so we could do better than they did. Watching my father go off to a dangerous job every day didn’t “prepare” me for work, but it did help me grow up with a sense of “work is part of adult life” that I wouldn’t have gotten if he’d spent every day watching TV and drinking beer.
