From our perspective (I'm a health policy person based in Europe), US health care is staggeringly expensive, very variable, and very unfair. It's the single biggest cause of personal bankruptcy in the States.
Your health is poor, overall, especially you have poor child health, and relatively poor maternal and infant health.
A large part of your population have no access to good quality health care, and this imposes large costs on your society.
Your major companies find high health care costs for staff a major burden, and this sharply reduces the competitiveness of good US employers.
You have the highest administrative costs for heath care that I know of, now running over 30%, and at current rates of increase, in thirty years you will be spending 100% of your GDP on health services.
At the top end, there is no better health care anywhere for acute illnesses, but very few people can access this.
The proposed changes are a start, and only a start. With no public option, there is a real risk that the insurance companies will continue to combine together to rip you off. However, the current proposals will save a lot of money over the next decade, which is why the insurance companies are spending millions buying ads, and influencing politicians to stop the change.
I hope it passes!
