Having lived in Europe 10 years (I am from south America), it is crazy that the rest of the world doesn't follow Europe's health coverage: everybody is covered, all the time, you can be covered either by public insurance (was my case) or private. There are no preconditions. Kids get covered for almost everything up until they are 18 or 21 (don't remember), drugs for adults is only 5 euro each. No matter the cost. And it just works.
By the way, Private is cheaper when you are younger, gets more expensive when you are older. So if you choose private, under very phew circumstances you can switch to Public.
In the other side, you have the US health care which is probably one of the worst in the world. Crazy.
