Oh, I never disagreed about “unskilled labor” I tried to make that clear in my first comment, perhaps I failed in that. As I said “unskilled labor” is a term used to denigrate essential work that society chooses to look down on. 

That said, that wages are often low in these work areas is a function of labor competition rather than capitalists or capitalism seeking an excuse to pay poverty wages. 

That such low wages exists and insomuch as the workers can join and leave voluntarily (ie they are not slaves, waged or otherwise) suggests that there are people who can achieve more than subsistence on such pay. This is simply the nature of labor competition.

So perhaps we are in argumentative agreement here overall 😂
