Market is a term that can be used to describe “an area or arena in which commercial dealings are conducted”

You can absolutely refer to the US economic market or African market and the participants there in. If not I would love a reference to explain otherwise.

Of course different kinds of labor receive varying compensation and these things depend on the level of skill and demand. This isn’t a question of whether everyone should be paid equally. It’s a question of how to resolve growing income disparities between top earners and low earners, specifically asymmetric income growth. Top earner income is rising at amazing rates while low earners are seeing meager increases. This has been ongoing for decades. There is an entire discussion on it here so I don’t think there needs to be any more elaboration.
