Thats got to be fake. I've never seen white guys build a house. Wheres all the mexican guys? There wasn't even any mexican music blasting. How bizzare.
Around here 95% of home building is done by immigrants. All the flat work, framing, roofing ,paint and flooring is done by them. even the mechanicals are getting there now. About the only thing not done by them is data/security. Close enough isn't good enough in those areas.
The PNW must be somewhat isolated still. I follow another guy on utube, Essential Craftsman and he built a spec house there a while back. Same way, No mexicans at all.
