The thing with healthcare is that some level of care gets provided whether the patient can pay or not. So that raises costs overall. Also not getting healthcare makes other people less healthy. Opting out of the system screws it up for everone else. A reform was needed, we got one though it had flaws, and yet people complain about being required to pay for insurance. But America is still in a individualist oriented mindset, as in it's all about me and everyone else can go screw themselves.
Yes the two party system is screwed up. But it wasn't designed to be that way, it just happened due to the nature of the rules set up and the environment it takes place in. Winner takes all, lack of communication, complexity of understanding the issues, etc. So where other countries might have a coalition that takes place after a general election, we have coalitions that are formed during the primary elections which naturally end up being dominated by extremists and true believers in their party and not by moderate voices.
And Trump doesn't really run businesses, he mostly invests in them, lends his name, etc. How the country will be run if he's president is a complete unknown at the moment because it all will depend upon who he gets in the cabinet, the people who might actually know how to run things (if we're lucky). With Hillary everyone has a pretty good idea of what names might be in the cabinet and actually deciding policy, and we know if we like or dislike them, but with Trump everything is a huge unknown (huuuuuge).
