This is an interesting perspective. I've seen both sides of the coin. I've personally had hard work pay off significantly and at the same time it is what I wanted to do personally to challenge myself. I didn't have to.

I've also seen incredibly hard workers lied to and promised things only later to be told did you get it in writing?

It is hard to have your perspective when the job is menial, imo. Not a ton of personal growth as a garbage man or general laborer.
