So presumably clothing isn't a need, since you can often survive without it?
You might want to tell that to the Tahitans.
For economic purposes, needs are generally seen as: Food, Water, Shelter, Clothing, Healthcare/Medicine (not to say everything in those catagories is a need of course; caviar, distilled water, a mansion house, leather jackets and cough sweets would all be wants not needs, despite fitting in each catagory respectively).
No, that is a very recent "need" and is truly not a need. I mentioned the necessities of life, not the things to make life easier and happier. YOu do the same thing that is happening in this country now. Your arguments can be applied to TVS (got to know when that tornado is coming, right), Phones (got to know when the Abombs are falling) or even cars (to outrace the devil). But in reality those are wants, not needs.
That you would be attempting to compare healthcare to things such as a car, a phone, or other luxuries demonstrates just what sort of a gulf there is between the two. I can live without a phone, I can (and do) live without a car. I can live without fine foods, or designer clothing. I can live without a fancy house, holidays abroad, wine, cigarettes, etc. etc., but not healthcare. If I get a disease, or a severe injury, or [insert any other life endangering health related problem], I need healthcare
No, you want health care. Others want cars. SHould I make you buy a car? To some that is the decision. But you can do without health care (live in the country) or the ones that "need" cars can move to the city (and worry about health care because of the polution and muggings). But neither is needed. Both are wanted - by some, not by all.
