It's not about the healthcare itself. It's for the people. With the current system, not everyone can get help. Later this year, I, myself, am set to be without any form of healthcare for a year before Obamacare kicks in for me. If I break my arm, or get really sick during that time, I'm screwed(and by the way, I'm quite fragile and somewhat sickly). I can't afford healthcare, and neither can my family.
With universal healthcare, that wouldn't be a problem. Anyone could just go to the hospital to get healed when necessary. I fail to see how that's in any way problematic.
Don't you have health insurance?
