Or young people just starting out and have only ever worked in a booming market. I worked in construction/sanitation for a family member's business from 15 to 18 summers, then 18 to 20 full time. My dad always stipulated that my job was entirely dependent upon going to night school and keeping my grades up because he did not want me to follow that path in life. He was only a little older than I am now and was already suffering from physical problems associated with such labor. So he really knew what he was talking about. It was good advice because The Great Recession nearly bankrupted the company. I also see people that have overinflated ideas of wages in such industries. They often quote average salaries in the range of what the BLS reports as the 90th percentile.
