>they are paid nothing, zero,
Incorrect. Disability, social security, etc are payments. Payments that we all bear when people, rightfully, opt out of this oppressive, toxic, dog eat dog workforce. Or worse, when someone's body is sacrificed for the sake of profits. If you're getting rid of minimum wage you should probably get rid of all social safety nets to deal with perverse incentives.
>because well-intentioned but economically clueless people have decided that it’s not morally proper for low-skilled people to make whatever their labor is worth.
eesh. Let's play out what happens when you treat human beings like livestock, from living memory: We get the company town(1). We get China's foxconn suicides(2). We get slave labor camps (active in China and the United states, like today, right now(3,4)). Then, or concurrently we get death camps for the infirm(5); if we can't hope to pay even a subsistence wage for all labor then how can we possibly allow these parasites to live on, homeless and impoverished, with the ills those kind bring to a civilized land.
>No, it puts a floor on who is employable, hurting the least capable people the most.
That's merely a point of debate, not a fact, as you suggest(6). In light of the cited history I've outlined, I would argue that such an argument is debunked and does not merit further discussion without extraordinary evidence.
In regards to your last statement. What you've arguing for has been tried before, and is explained, with citations, for you to read at your leisure, on the Wikipedia page for minimum wage. I beg that you take a cursory examination of the available history and literature. I would rather like to avoid repeating the bloody mistakes of history.
