There are factors beyond an individual's control.... like the tax code. It's impossible to make a completely neutral tax code. It's always either going to be more favorable to the wealthy (supply side) or to the middle class (demand side).
That is a misnomer. Supply and Demand differ wildly depending on what is being supplied and demanded, and generally include both wealthy and middle class (who are also wealthy).
Which bit do you need explaining? It’s no secret that many employees of these sorts of companies require governmental assistance to augment their low wages.
Many low-skill workers do indeed receive some form of government support, as we have broadly expanded the scope of those programs.
But you are making a leap to "therefore companies are benefiting by that much", when that is not in evidence.
For example, my son started working at minimum wage when he was 14, scooping ice cream at a local joint. If you had cut - say, Medicaid - on a Thursday, there is not a single forcing function in the world that would have forced that employer to increase his employee's hourly rate on Monday. The same is true of the Hardees down the street - who also would not have had to increase wages if Medicaid had been cut.
Their labour produces the wealth,
Respectfully, it does not. Labor
assists in producing the wealth, in cooperation with capital, planning, and other inputs.
If you would like an example, a simple test: Choose the hardest worker you know, and have hem plow a field with whatever tool they can make on their own. They can have 10 hours a day to work as hard as they like. I will compete with them by merely sitting on my butt, for 5 hours a day atop a tractor, which I will use.
but they are not sufficiently compensated for it
If their labor is worth more value than their current compensation, then they have a fantastic opportunity - they can point this out to gain a raise, or, should their employer refuse to pay them what their labor is worth, they can go work for an employer who will.
Unfortunately, many people's labor is not at worth what we wish it was. If someone's value added on a job is less than $8 an hour, then that means an employer cannot afford to hire them unless the
total cost (salary, benefit, tax, regulatory, and training) of doing so is
less than $8 an hour.
and instead rely on the taxpayer to survive. Even if your claim about these sorts of jobs reducing government services is true, it still doesn’t mean the wealth isn’t stolen.
It is not stolen. IF you wanted to apply your framework, then the actual result (see point about reducing government services) observed would be that corporations that offer low-skill positions subsidize the government, not the other way around.
I don't agree with that framework, because those two things are not connected. If the Government were to increase (say) TANF payments by 10% tomorrow, Wal-Mart could not get away with lowering it's salary by a commensurate amount the day after. If the Government cut WIC entirely, BurgerKing would not be forced against its will to raise its wages.
