I was simplyfying to make the example clearer. The overall point I was trying to make is that adding marginal workers can raise average wages if employers pay the new workers more. (And thus, they don't, and complain of a supply shortage)

Is there a word for that?

Pointing out the "fallacy" in an incidental point I made isn't really constructive. Because I think you're agreeing that if new hires get more pay then so should existing workers.

You took as arguing that that shouldn't happen, but I wasn't arguing that.
