You're only thinking about work stress. If you only make $10-12/hr your concerned about putting food on the table, making your mortgage payment, buying clothes for your kids etc. So tell me, would you rather have a stressful day at work and head home knowing you're financially secure? Or would you rather have a low stress job but when you head home you don't know if you'll have enough money to buy dinner. The answer is clear if you ask me.
Edit. So what I'm saying is be grateful, not greedy. We make 80k+ to drive a damn truck. If we have issues with the company it certainly shouldn't be about pay. If anything I would like shorter days. I'll take a 10k pay cut if I could be headed home around 6-6:30 everyday.
