Trade jobs frequently require buying a lot of the equipment and protective gear. Most of the high pay examples include a lot of overtime, and may be limited when work isn’t available. A lot of trades don’t have a regular 40 hour work week, if the weather is bad for a week they may not make any money.

It really depends and is a lot more complex of a comparison. Trades are important and I think they should have more stability and require less personal cost, although most of that would be addressed if we had single payer healthcare and UBI.
