"Deserving" and "undeserving* are made up concepts disconnected from any concrete reality, just shards of Christianity preserved in the amber of American civic religion and exported throughout the capitalist-dominated world. If you talk about who "deserves" this or that, you might as well be talking about who's holy and who's a sinner. The truth is, we are just animals who banded together tens of thousands of years ago to help each other survive. Many anthropologists say that society began when we started taking care of those who could no longer contribute as much physically: the old, the sick, the injured. But hey, if you want to be less socially evolved than a bunch of cave-dwelling hunter gatherers, that's your choice. Just don't expect the rest of humanity to entertain your rotten ideas about useless eaters, and don't act surprised when you find yourself put out on the ice.
