I see, every time I go and down the NJ Turnpike, the ad for the local heavy equipment union - right in front of their "training area", with cranes, dozers, etc. So it's not necessarily not happening from my perspective.
I just went through some contractor invoices for one of my government clients - they have to pay the guys prevailing wage - the apprentice was making $14/hour. Anyone with a level of skill and experience was not less than $30/hour. Top level guys were making $65/hour.
I don't know if they work 2000 hours per year at those salaries, but these are some good numbers, for that level of education.
Get into some of the trade unions in NYC, and they sky could very well be the limit.
I was a Heavy Equipment Operator in the military. After my discharge i peddled myself like the my pillow guy, i could operate anything , and i mean anything , dozers, all cranes, graders, snow removal for flight line, dragline, scrapers and much more, i forgot to mention tractor trailers . Guess what ! no one would hire me. Why? , i wasn't in a union.
The same problem exists today, get in a union, very difficult, like teaching, or electrical workers or any trade. YOU GOT TO KNOW SOMEONE, so the sons, and nephews, and now the daughters and nieces get in. Don't get me wrong, some people have the passion to follow in their parents footsteps, but most could care less.
I went to night school for welding, and electrical, and eventually became a Master Welder, I'm retired now but i had my resistance, and road blocks, mostly losing one job 12 years to Asia, and 25 years to Canada. I had to get a job at 59 years old to the sneers of my interviewers but eventually landed not one but 2 different jobs.
My opinion is anyone can pick themselves up and find employment, blue collar, white collar, it's tough but doable.
