What's your definition of exploitation?

There's is poor people who exploit other poor people. Poor people that sends children to work for example. Only the rich can exploit? You are not using the definition of exploitation from the dictionaries. A stronger or armed person has a power differential with a weaker person. A smarter and less smart person too.

So, exploitation doesn't seem to be related exclusively to wealth inequality. It's a moral thing, not a matter of wealth differences.

A simple narrative of "us-good VS them-bad" is reductionistic.
