The congressman from the district where I formerly lived in VA was against health care reform because 'a lot of people who don't go to the doctor will go if it's passed'. I kid you not - and this was supported by a lot of his constituents.
For those who have good insurance, I hope you NEVER have to sit in a hospital as I did with a child who needed heart surgery....and no insurance to pay for it. Thankfully in our case a charity covered the cost (this was in 1971, so this is NOT a new problem among the poor). I also hope you never have to face being told 'no coverage' after you change jobs/insurers, which was common because of the broad-based preexisting conditions clause. Or have a serious condition go untreated because the insurance won't cover certain drugs, or a certain procedure. Health care in the USA is great, when you can get it - this should have been termed 'health insurance reform'.
I can go on all day, but bottom line, until you've been there, you don't know what hell it can be if your insurance goes away, or they just say no. And BTW, I once worked for a major insurance company in Chicago, paying medical claims. Even back in the 70's, there was a lot of emphasis on 'denial of benefits' and how NOT to pay the claims that were submitted.
