I said "in principle". What about birth, pregnancy, broken limbs, toothache, chronic head pain, broken joints, going to a morgue etc.? I mean, you don't HAVE to do any of these healthcare-necessitating things in principle during your life, but the chances of you actually not doing any of them is almost zero. The example is analogous to your mentioning of roads; that is EXACTLY my point! A vast majority need to use a hospital/healthcare at some point, a vast majority use roads at some point. What's the difference? Personally, I don't use the roads every single day, but I do have a cold quite often. There is literally no substantial difference here. We don't use national defence every day, but it is still paid for entirely out of American tax dollars!
"Also, I do care about people that is why I believe we should pay more people's protection, ability to transport, ability to send mail, etc. DA!"
..and healthcare!
