The GOP is just as fucked up as the Dems. They both have their colllective heads so far up their asses they do not see what the issue actually consistes of. The insurance is not the problem. The problem is the inflated costs of health care. Tort reform, Price regulation for drugs and medical treatment, purchase ins across state lines. This is what needs to be fixed.
You have the problem identified correctly, but not the fixes. Yes, tort reform will help, but it is a teeny tiny driver of the costs. Do it, but don't expect prices to drop noticeably.
I also think that price regulation is often a very short-sighted fix. Yes, it fixes the short-term problem at hand but price controls are notorious for creating many more problems in the future (notably lack of supply or supply that is done as poorly and as cheaply as imaginable like slum lords). What we need to bring down prices on drugs and medical treatment is competition. Drugs with a single supplier are going up 5000% not because of lack of regulation, but because of the single supplier part. I actually agree with Trump on this portion: if the government helped pay for the drug development (and thus has patent rights) and if there is a sole-supplier that is jacking up prices, then the government should have the right to be a competitor.
The main lack of competition is with doctors though. Many small cities around here (think 25,000 people) have a single person who does a type of medical work. Thus, these specialists are making $500k a year and up. We need to break the AMA control and produce more doctors. Two specialists each making $200k is cheaper than one making $500k plus the patients get far better care when the specialists have twice the time to think about and interact with their patients. And no one, democrat or republican, is serious enough about health reform to tackle the AMA strangle-hold on supply of doctors.
Purchase insurance across state lines has been around for years and years, yet it is always a dismal failure. Hoping that would fix this issue is just blind hope. The only way for this to happen is for states to decide to normalize their health care standards. With 50 different complex laws, regulations and systems, very few insurance companies ever even consider crossing state lines. This fix first needs to be done at the state level, then maybe purchasing across state lines might be of help.
