I think if you really want to make a proper living from the trades, you need to at some stage plan to move "off the tools" and into starting your own welding/plumbing/whatever business.
If you can do that successfully, you can get FAANG money.
Well there are around 130K plumbing businesses in the USA and around 400K plumbers, so I think that plan leaves around 270K plumbers snaking drains until they die.
