This post has to do with health insurance, specifically that offered to America’s senior citizens, and so will be of limited interest to younger people. Nonetheless, it does not hurt to understand the concepts behind private health insurance. It can and does work in other places, notably Switzerland. It does not work here.
Here’s why: In Switzerland, everyone must carry health insurance offered by private companies. Unlike here ( before Obamacare), insurers are not allowed to turn anyone away. Further, Switzerland mandates basic care offered by insurers. Swiss citizens are free to buy better care than basic, such as private rooms and better meals, but decent and affordable care is available to all.
