I interpret your story as the American workers thinking "wow, I'm not getting paid enough to deal with this s***."

I also interpret your story as the children of immigrants realizing "wow, I'm not going to be paid enough to deal with the s** * my parents deal/dealt with." So they find a way to get a tech job or desk job.

One could just as easily denigrate the children of immigrants as being lackadasical, but that's not necessary. Why denigrate people?
