That makes perfect sense. My comment was more pointed at those who believe people who have the option to get university degrees and enter white collar careers should instead go into trades, because they would make more money that way. I have seen it often that engineers making 100k are lamenting on HN about studying engineering, saying that if they had gone the trades route they would have earned the same or more from an earlier age and be better off financially. Every thread about university education is full of people advocating steering young people to choose trades over university, because instead of starting their life with a load of debt, they can start earning a good salary at a young age.

And I am sure the above are true for some people going to trades. But unless the average tradesperson's earnings improve significantly, I wouldn't recommend it as a general advice.
