Aren't blue-collar jobs, like construction work, essentially a life of traveling for work?

Even if welding, electrical work, plumbing, tiling, and other skilled construction jobs are all considered good,
won't you ultimately end up living a life of wandering all over the country?
If it's not a 5-day work week but a 6-day one,
there won't be time for dating, and even if you get married, wouldn't your wife end up having to handle all the childcare alone?
