On the other hand the family sized ones do jobs that aren't economically viable for a large unionized one because of too much overhead. The difference between a large construction company and a small one remodeling your home can be in the five figures. I think it's not fair to say that a family one lacks career advancement, it's like saying that a small web development shop doesn't have the same career advancement opportunities as Microsoft. It doesn't mean that working for a small shop is a dead end job. In reality an experienced tradesman is always in high demand by larger firms or has the ability to be an independent contractor, regardless of where he started. In large cities a licensed plumber or electrician can make six figures and trying to get them to come out to your house can take weeks because they're so busy. The independent nature of the work makes it very resistant to national franchises, and different start ups have tried to make "uber-like" services for contracting tradesmen, Amazon has tried upselling "pro" installation services but nobody's been able to really centralize it yet.
