This is over 20 years old, and I'm sure doesn't hold true in all areas, but at least at one point there was high demand to be a "san man" ("san" as in "sanitation") in NYC:

> It's a coveted job to be a New York City san man. When they last gave the qualifying test, 30,000 people took it. The General waited five years after passing the exam before a job came open, which is typical. And though the work is grueling, the pay-- if you're actually on a truck-- starts at $40,000 and can go to $60 after just five years. [note: this is in 2003 dollars!] A good winter, meaning one with lots of overtime for clearing snow-- they clear snow, too-- can make for a $90,000 year for a senior guy.

These guys are/were unionized, which certainly helps.

And that's how it should be. Trash men should be making $200K and have high social status whereas the devs helping Bezos to his 5th super yacht or Zuck poison more kids should get minimum wage and treated as pariahs. Unfortunately at the country level it's reversed.
