As I don't have a lot of time in the moment, my post on the history of American health care will be a very brief one. And anyway, all I could have done would be repeating what others said somewhere else. So I wanted to share those pages I like most, each of them with a unique way of presenting the facts. They all address the issue of the historical context of the current debate which I think to be a helpful hint for a generally better understanding.
The Public Broadcast Service (short: PBC) offers an interactive timeline including exactly as much information as I think to be good as an introduction to the topic: not too much, but fairly enough. It starts in the 1900s.
This video concentrates on the developments since the 1940s in a very simple and entertaining manner and is able to illustrate even rather abstract aspects quite well:
Up to now, I did not find sufficient information on the time before 1900, but I will add it as soon as I discover things worth sharing.
