I don't care that much about "labour issues" because it seems like a logically flawed avenue to explore to begin with.
To be financially successful under any market system I can think of requires you, in a mathematical sense, to be close enough to the top within a company that you get a greater proportion of the profit than simply 1/employees.
In simple terms - I can't employ a maid unless I earn more than a maid, a maid can never be paid enough that I would want to be a maid (being the maid's employer, or at least having that optionality, is strictly superior).
Some jobs have comparative advantage, e.g. I might enjoy working on my car but know that a mechanic can do the same job in 1/10th the time. But a lot of stuff is just straight - I earn more than you, you do it for me, so I can get more things done.
