If you learn more then you would understand why most of the able countries are going national health. This, to put USA to shame, including Mexico, our poor neighbor to the south. Accessible health care is a matter of moral of the country and society. It does not need to be everything for everybody, and should be rationed, but it does need to be minimum sufficient. The reason for hospital closing doors is exactly why we need national health insurance. The hospital cost is about 30% of all health care cost. They have to do cost shifting to cover the charity work they done. So in essence, your payment is higher, or your insurance is increasing because those uninsured could not afford or not willing to buy their own insurance. So you think without the ACA you don't pay for them, think again. With the law passing, and the individual mandate, theoretically, the cost will come down. We will wait and see.
Another thing is, the US healthcare industry is one unregulated market which should not be that way. The number of doctors are controled by AMA, the medcation is priced as high as the market can bear which is way higher than the international average . By the way, Canadian medication is about 1% higer than the international average, but is dramatically lower than what is available in the US market.
