Probably because you did actually have to work for all of those things throughout the course of human history. Just because you're born doesn't mean that you're guaranteed things any more than a random monkey born in the wild is guaranteed things. I don't think that anyone thinks that a basic amount of food is a luxury, but when you start saying that you want your food stamps to pay for Doritos and Coca Cola, then yeah... you're going to get people saying some shit. When it comes to a lot of the other stuff, people all over the world manage to live without those things and rather than thinking that's a terrible state of affairs, we tend to point to those examples as evidence that you don't actually need these things and that they are luxuries that you should earn rather than have handed to you.

Having said that, we do have varying degrees of social welfare programs that provide assistance for basic needs (how effective they are largely depends on the state you are in). In general, however, the American cultural attitude toward government assistance has always been kind of like the Dark Souls community where people are just told to "git gud" and flamed for being losers if things are not working out for whatever reason. It's honestly a pretty toxic mentality, but it's not likely to change any time soon thanks to brainwashed morons that find some twisted virtue in voting against their own self-interest. The number of people on welfare and entitlements in this country that bitch constantly about welfare and entitlements is honestly comical.
