Maybe it varies by area. My sister watched a lot of renovation in her neighborhood in NC and told me, “The Mexicans do the roofing, the blacks do the framing, and the whites do the plumbing and electric.” Just her observations but it seemed the same here when our neighbor built their house. Before anyone screams racism, these job choices are the workers’. The contractors will hire anyone who is qualified and shows up not drunk.
We still have plenty of lazy white people here, don't get me wrong. You still see Mexicans on construction crews here, but they are still mostly working the large corporate farms. Cedar Point amusement park, about 15 minutes from me, is starting their summer hiring. 5000+ people. They hire a lot of people from Europe for the summer and have their own dorms, too. They can't get enough locals to staff it anymore.
