Here, let me dust off a chair so your *** does not get dirty.
I take it you do not have an engineering degree? You never worked in construction did you? I managed people in the industry for 40 years. I take it you never worked in manufacturing either? You will find the men and women who work these jobs are used to these hours. Shift work, and there are three 8 hour shifts in many industries and professions (Medicine), is quite common. It must be nice to work in a job where the worst thing you have to worry about is a paper cut and where you go for lunch.
Oh, and your comment about getting a good education is nonsense and shows your ignorance. Many of us who worked these jobs earned enough to own homes, send kids to college, meet the bills, and live good lives. I know men who work in the trades who earned over $150,000 a year and built businesses they own becoming millionaires. You will find many of those men on this site.
You must be a kid, or stupid, or both.
