Just like how many of them dream of white collar work at their mine/construction site/shop. The difference being is that when they find some white collar work, they no longer dream of blue collar work (because it sucks and kills you a day at a time).
It depends on what blue collar work you're talking about...I went blue collar (power plant operator)...obtained CS degree and got a job as a programmer...then after a year went back to blue collar...operations is more interesting to me, plus I get to be on my feet, moving around all shift...it suits me much more...plus the pay for an operator is >$140k in a rural area
Only the ones who have never worked them before lol.
