I understand your position, but there are plenty of variables that make that plumber or electrician much better off than the lawyer.
Not on wages, which is really the only thing that matters.
I'm sure you can live a nice, modest life as a plumber; but if you have ambition and drive, that's not the area you'll want to build a career because there's isn't really any room for growth. Like, there's working for someone and owning your own business...that's it. There's no ladder to go up, no leadership position to aim for...and again, that's perfectly OK.
But if you have ambition, it's probably not OK.
You have a massive head start out of the gate, and your field puts you in a position to acquire houses at a severe discount because you just happened to be in the right place at the right time.
OK, but that's luck, and that's not in anyone's control.
You might have a massive head start out of the gate because you don't need to pay your dues like you have to in other areas, but your growth (personal, economic, fiscal)
will stall out far sooner than the college graduate's.
By the time a lawyer is a partner, the plumber could be a real estate tycoon.
Well, only if things break for them that way, which it is almost assured that they won't because it's completely out of their control, whereas the lawyer does have significant control
and far more opportunities and options to control their career trajectory.
With a plumber, it's work for someone else or work for yourself...there's no ladder to move up there, so there's less ambition...and that is perfectly OK for people with low ambition.
It's not a mindset that I have or would encourage, but it's certainly an option.
