A sibling lives near an old industrial center; he drives truck for Sysco. We occasionally discuss different careers. Tool & die makers near him don't make more than truck drivers.

I'm sure there are some examples -- if you can do eg old-style timber framing for people who can afford 10-inch old growth timber and want 30+ foot ceilings, there will always be a handful of well-paying gigs.

But how common are these jobs for people at the, say, 70th percentile of skill rather than 95th?
