> 1: Strawman. The issue isn't "make a mint doing unskilled labor", it's "be paid enough to survive".
I never said anything about "making a mint" flipping burgers, so .. "strawman" right back at you, I guess.
But you need to understand that no one else is obligated to pay you "enough to survive", regardless of what you're capable of. Have you ever run a business? If you did, you'd find yourself paying your employees roughly market salaries, because that's what their productivity is "worth" (to you and your business).
You could be greedy (and/or a scumbag), and pay them below market, or you might be smart and long-term oriented and pay them above market rates (because it's in your personal interest to keep good employees around - they're not easily replaceable after all).
But the bottom line is that business are not charities, and they can't just pay people whatever people want - especially when people's desires are infinite - they have to live within their financial constraints, placed on them primarily by their customers.
McDonald's doesn't pay minimum wage just because they're mean. They do it because anyone off the street can flip burgers and cook fries. The productivity of an entry level employee flipping burgers is just not that valuable.
> 2: There are circumstances in which pay for mundane tasks (or goods) can be quite high
Sure, but that doesn't mean that all mundane tasks are valued as highly.
Value is subjective, by the way. Which means, among other things, that you can't tell someone what they should be willing to pay for Person X's labour - that's up to the potential employer to determine for himself, based on his subjective preferences, valuations and prioritizations of his means and ends.
Based on the exact same principle, no one can "correctly" tell you what you should be willing to pay for a fruit smoothie tomorrow at noon.
> People are paid the SUBSET of they value they produce for their employers they can claim under prevailing market conditions
Again, businesses are not charities. They need profits, and their owners want profits - that's why they're in business to begin with. What they deem an acceptable level of profit for their own businesses is subjective, and up to them.
The same works both ways. Employees decide under what conditions they're willing to accept Job X.
