I spent about a week at a natural gas power plant in Oregon being built to work on some telecom. Welders there ranged from 80k-120k that I knew. To be fair, I don't know of any welder above water that could make 150k. I only know the 150 range to be for deep sea oil guys. But that's just my experience. Either way, it's not like you get out of the gate being that class of welder. It's getting cert'd in difference environments, tolerances and types of welding, along with experience that get you to that level. And I don't know a single career blue-collar that thinks otherwise. Unless they're really stupid and anything above 30k a year is unbelievable to them.
"You mean you have to develop extra skills that separate you from the herd to get paid more? No! Really?" Same goes for programming too if we're all being honest.
