I belong to the Kaiser HMO in California. They saved my life when I had a burst appendix. Their health care has improved dramatically over the years and I now consider excellent. I believe one of the reasons it provides excellent health care at competitive cost is that it is a NONPROFIT CORPORATION. It is run by doctors not accountants for the benefit of their members, not investors.
Other countries, like Holland can have excellent health care without breaking the bank. Unfortunately the US is so politicized and dominated by corporate interests that good health care for everyone seems impossible.
