You're wrong - there's not "a lot of avenues" for the trades to make "well over 100k or 200k."
Median pay (2022) from the U.S. BUREAU OF LABOR STATISTICS.
Welders: $47,540 per year https://www.bls.gov/ooh/production/welders-cutters-solderers...
Plumbers: $60,090 per year https://www.bls.gov/ooh/construction-and-extraction/plumbers...
Electricians: $60,240 per year https://www.bls.gov/ooh/construction-and-extraction/electric...
In the past Hacker News comments also claimed truckers were very highly paid
Heavy and Tractor-trailer Truck Drivers: $49,920 per year https://www.bls.gov/ooh/transportation-and-material-moving/h...
We can compare those numbers to
Software Developer: $124,200 per year https://www.bls.gov/ooh/computer-and-information-technology/...
Maybe some individual plumbers are making hundreds of thousands of dollars, but they are an extreme outlier. The other question is how many hours are they working a week to make that much? I'm guessing you either have to work lots of overtime or be a business owner.
I have a lot of friends and family in the trade and the trucking industry. I made more than every single one of them and they all work more hours than me. The one friend I have that makes "almost $100k/year" works almost every weekend to make that.
