Well, the post you quoted was in response to rufus who wrote something like "socialize needs, privatize wants." My point was this.
First, people are quick to include healthcare in the "needs" category, like somehow it's written into the Magna Carta or something as some sort of basic human right. I don't necessarily agree with that, but I recognize opinions may differ. I've always viewed it as a quality of life issue.
My second point was that if we want to get into the "wants vs needs" debate in terms of socialization, I think there are things that human beings "need" way more than they need healthcare, such as food, water, and shelter (maybe even include clothing in that). We socialize water, at least for a good chunk of the population, but I think that was done more out of practicality than out of a decision that water is a basic human right or need.
But we haven't done it for food or shelter, and I'm not sure we should. Again, I believe that "socially" we can do things to help or assist those who need it, but I don't think it just works for us to decide that government is now going to provide all food and shelter to us, paid for by the collective. But again, just my opinion.
