No, they're simply not linked. That other people need stuff is a fact. I'm not averse at all to society helping out people with genuine need. My personal viewpoint is that my place in the world is just a moment in time. I as well as my family and friends could be in very different circumstances in the future. For that matter, some of my family are really not well off anyway. I just disagree with the notion that because a subset of people can't provide something for themselves, we should have the government provide it for everybody. There's another option, that being provide it for just the people who can't provide it for themselves who actually want it.
Homeless people need somewhere to live, but that doesn't mean the government should start building houses and assign everyone one. Some people don't have food, but I don't want a government ratio crate on my doorstep every week. I want the right to pick my own provider, and the right to fire them when they do a bad job.
