It's a complicated problem. We exist in a universe founded upon the principle of entropy - which means that our existence is predicated on collecting energy at a faster rate than entropy can destroy us. From the universe's perspective, we don't deserve to exist. Yet, we know that the laws of the universe are not honorable or good. We know that humans are a victim of philosophic "thrownness". We are victims of being thrown into a world that forces us to eat or be eaten. There is no evidence that we deserve to be thrown into a harsh world. There is no evidence that we did something before birth that justified throwing us into a situation where we will suffer and die.
We have found ways of working together to produce tons of collective resources. Maybe in a "resource scarce" world, a harsh ethic of "earn your living" is justified since everyone is barely making it - no one can afford to assist those who aren't being productive.
But, in a modern society where the means of production are so complicated that it isn't fair to treat people like they must "earn a living". If you don't give people free access to land for farming, if you don't give people free access to bushes for foraging, if you don't give people free access to waters for fishing, if you don't give people free access to forests for hunting, then you can't completely blame them for not having the resources needed to survive. If a nation restricts resources, then it has the obligation to care for those who are restricted away from the resources that they need to survive.
Also, evolution doesn't care about the sick or disabled. Evolution is fine with letting them die so that better genes evolve. But we are more honorable and loving than evolution. We understand that the sick and disabled are victims of their circumstance. They are victims of being "thrown" into a bad situation. They don't deserve to suffer and die. We live in an age of plenty. Our factories and supply chains give us way more food and resources than we need. It seems like the most loving strategy is to be generous with collective resources and help everyone avoid suffering.
Do people deserve to live? The ontology of the universe says no. Do people deserve to suffer and die? The metaphysics of "thrownness" says no. Should we treat people as if they deserve to live? If we care about collective wellbeing in a resource abundant society, then I believe we should.
