Folks really should be encouraging their kids to do things they like and are good at. That might include a college education or heading toward the trades. Encouraging a square peg to fit into a round hole is unlikely to produce anyone with a high income - college or plumbing. There are plenty of folks in the trades who are unsuccessful in what they do because they weren’t really designed to be good at them. It’s not their talent. Read some bad reviews, etc. Even in engineering, part of what my H does is fix what other engineers messed up. Those folks rarely stay in the job long. It doesn’t mean their college failed them. Others from the same college do well.
Help kids find their niche rather than trying to fit a kid into a niche.
