Then, of course, there's unearned income -- very much so related to the topic of "stock ownership" that started this thread -- which, by definition, is acquired not through any meaningful contribution of labor to the "economy", but instead as a reward for the incidental private claim to profits our economic system happens to allow to people.

They still do a big chunk of the work.
