The problem here is, most peoples' wages are defined by their leverage, not their value. For people in those situations, the benefit of minimum wage is that most people below that wage immediately get leverage in the form of legal requirement to pay them (or anyone else) min wage. This isn't a matter of improving the situation for everyone, it's a matter of improving the situation for the majority of min-wage workers. If someone genuinely can't provide $10/hr of value, then either 1) they need to upskill (and there are social services for that, although perhaps not in the US idk) or 2) they're like one of those literal retards who are becoming literally unemployable, and the solution is either to subsidize their employer (which is okay in this instance because you're not subsidizing a race to the bottom like you are with subsidizing normal e.g. McDonalds wages) or put them on a disability pension. But realistically, most people are capable of upskillinng and that's what they should be doing if they're not valuable enough to an employer.
