I think it can be subdivided into value creators and value movers.

A comedian, doctor, farmer, or teacher creates value. They directly produce something that benefits other humans.

The financial sector, marketing, sales, real-estate conglomerates, etc I see as value movers. They don't actually create something themselves, but rather move it from someplace else to themselves, thereby forcing others to play the same game not to get outcompeted. It's pretty hard to argue marketing or hedge funds aren't a zero-sum game.
