On: Jobs people are most likely to inherit from their mother and father

I was thinking the same thing - although it's not really confounding as the results are still true. It's likely an explanatory factor though.

It's confounding in the sense that if a child has the same job as their parent, we assume that parental influence may have had something to do with it. Which it probably does, in a lot of occupations. But when the "company town" effect occurs, it's not necessarily because of parental influence. It's merely a lack of other options.
