LP, we argue that nobody but the employer who pays a person for doing the thing they do ought need to subsidize the person for doing the thing. If I need a human to do a stupid human trick, I need to pay enough to sustain that human to the extent anyone can be expected to sustain doing the trick and otherwise remain a well adjusted member of society. I object outright to your request that I must pay taxes so that mcdonalds can maintain wage slavery.
Either way, the same amount of work gets done. But in the higher work/wage situation, the worker gets robbed of less of their value added, and the owners still have more, they just don't have AS MUCH more. Will you really scoff at someone for wanting less of their value added taken from them by people whose only contribution was accidental?
But the human already exists. The employer didn't create the human and thus didn't create the needs of that human. Thus I do not believe the employer has an obligation to cover those costs.
As for "less of their value added"--you're simply assuming that they're being robbed in the first place. Since it's not exactly unheard of for employers to simply shut down if they can't pass on cost increases it's not at all obvious that they're being robbed in the first place. The "logic" showing such robbing always ignores many of the costs.
This is the same mythical infinite pool of profits argument that I have referred to many times in the past--you figure no matter what you take it's still there to take from.
