This isn't all that surprising. I mean, it's surprising a priori, but not post hoc when considering the social culture of the United States.

Construction is a job that you go into if you've been to prison, haven't gone to college, or are an undocumented laborer. It attracts those people who are the least skilled in the country because it's a hard job that's hard on your body, pays little, and is intellectually uninteresting (compared to most college educated middle class jobs). The people who make money in the industry have to go through onerous licensing requirements and have the skills necessary to run their own business and take on the risks of having that business fail, which most people (myself included) don't have. That's managing payroll, licensing, taxation (and avoiding taxation), sales, marketing, and all the rest of it while still being able to be a master plumber or what have you which can take 10 years or more. And even then you can be making 70+ hours a week or have to be on-call for emergencies (as a plumber), only be able to get work during certain times of the year (summer for a large amount of construction), or be away from home for long periods of time (if you have a specialized skill such as oil drilling or specialized skills in setting concrete and so forth and have to travel across the country to where the work is).

I've worked day labor in construction. After only a few months my hands are messed up to the point where some days it hurts to type after longer periods of time. Have you ever had to carry dry wall, lumber or sheet rock for 8 hours a day for minimum wage? It's boring and it hurts.

I'm currently unemployed and homeless. I'd rather be unemployed and homeless than do construction again. A year of that and my body would fall apart.

As a society we've made the industry as unattractive as possible so what do you expect?
