My place has a large shipyard and as story I got told is that good welder lands there with a private jet, do their welding then fly to the next place. I am guessing good welders have a niche market as well.
Great story, because it demonstrates what people often fail to think about in salary: your hypothetical maximum salary is bounded by the amount of value you add to the finished product.
If you're a key component (welder) in a high priced product (ship), the builder can compensate you $$$$ and still win. So they do.
You can temporarily have unreasonably high pay (higher than value added), but eventually the market will figure it out. The only way to make outsized returns your entire career is to find a supply-limited, high-value-add niche.

Yeah this is the part everyone is ignoring in the conversation. Many highly compensated physical labor jobs are highly compensated because of the associated risk. While being a developer (with exceptions) doesn't expose you to any physical risk.
