As an American parent of young children, I keep being told that college is a scam and I should steer my kids toward the trades. 90+% of the time, I am being told this by a white-collar worker who went to college themselves, and is just bloviating.
When we reach a real crisis point, severe enough to actually consider granting skilled tradespeople access to a fraction of the privilege enjoyed by white-collar workers, then I might consider nudging my kids toward electrician or plumbing work. But under the current social caste system, of course I am going to do everything possible to give my kids access to college and steer them that way.
I believe that virtually everyone, white-collar and blue-collar alike, quietly feels likewise. We make a pretense of giving contrary advice, but mostly just in hopes that other people will move in that direction for us. To take the bullet and help with this imbalance, and also to relieve the intense competition our own kids face.
