Very interesting perspective, and not one that I can agree with. I don't believe things should be declared illegal unless they are morally wrong or harmful. You may dislike private insurance, but it is neither morally wrong, nor harmful, IMO. Yes, that is a very American perspective - we do like our freedom of choice, and don't want to be constricted with laws created by people who have a different opinion than we do about what is best for us as individuals.
You are also way underestimating the cost of health insurance in Canada and other countries with universal healthcare. The monthly amount you paid is nowhere near the actual cost; the rest is baked into taxes paid through employment, sales tax, property tax, etc.
Finally, you absolutely do not know all about health insurance coverage in America. Far from it. You happen to live in a state that is quite well known for very poor medical care and lack of sufficient medical care providers (as do my in-laws who are currently very ill). Many of us who live elsewhere in the US have very positive experiences with our health care providers. Not to mention, your particular type of insurance coverage makes a huge difference. My insurance covers 95% of the physicians who practice in my state, so I can see pretty much anyone I want, without needing a referral, and with very short wait times.
Bottom line, I don't mind that you are expressing frustration about your negative experiences, and that you preferred what you had elsewhere. But I do mind that, having had some limited experience in a very rural area of this country, you believe you know enough to speak for the entire population of this country. Not so, friend.
