You're treating social conventions like fundamental of human nature. Altruism, including kin selection is just as natural as greed. Kin can be socialised to tribe, tribe to national. There are numerous countries where this has been successfully done. Where the incentive structure is not narrow self interest at literally any cost. Greed as the only motivator is reductive and a narrative that can be used to justify literally any behaviour, no matter how exploitative. It's an easy out for bad actors and broken systems. Healthcare in other developed countries simply does not work like this.
