@muehlfield@social.tchncs.de less money is worse than more for those in poverty. I think it would be hard to disagree on this definition of worse.
I would word it more like "Employers often benefit from a huge supply of unskilled laborers with low market value". I'm not saying that is entirely the workers fault, it is the systems. But I wouldn't paint the company as the bad actor here, the issue is a system which doesnt provide better means for unskilled workers to become skilled workers.
Generally a company isnt really exploiting anyone, they are just paying whatever a workers skills happen to be worth.
