There are standards for virtually everything. Meet the current basic standards. For food, a basket of FDA/USDA-approved for distribution food to make a basic but nutritious diet for the family of 4. For housing, you could go with minimums for HUD housing. For education, through public high school. These are not hard to figure out (but may be a bit tedious). These are also minimums required to maintain a functional workforce in a modern society.

Right. So what you want is a Dickensian crabs-in-a-bucket labor market where the wage level is set by the most desperate person, who will work for hours to get a crust of bread for his/her next meal. A market where employers can abuse workers at will because there really are 500 others outside the gate who will take his job if he isn't willing to take the beating?
We are no longer living in a frontier society where 97%+ of the workers are producing food.
That insanely over-simplistic model has been tried, and it is a resounding failure, both for every society, every country, and every individual living in it. Those societies inevitably collapse or grow out of it with minimum standards for everyone. And while it is obviously awful for the workers, it is no day at the beach for the oligarchs either, who must live in secured closed-off areas, always frightened of everyone in the public as well as their rivals in power. Unproductive misery for everyone is what you want?
So, NO, the solution is not to just make the people at the bottom more poor, more hungry, and more desperate.
The solution is to stop giving benefits by ensuring that their employer pays the workers sufficiently that they do NOT NEED benefits to survive.
If an employer cannot pay their workers a living wage they do NOT have a business model.
They have an exploitation model.
The exploitation model specifically violates your above principle saying that the employers have a natural right to the fruits of the workers' labor to whatever degree they can exploit the worker by their desperation.
You aren't saying the no one has a right to the fruits of anyone else's labor, you are only saying that no other worker has such a right, but the employers do.
You are saying that if someone has power or deception, whatever they can take is their right.
I say, NO, that is the most dishonorable and amoral of societies.
