For all those of you US mates of mine who are somewhat confused as to how things will operate under Obamacare, this chart should simplify it somewhat.
Under the old disorganised anarchic free enterprise model, you just bought insurance and went to the doctor if you needed to. This will free you from that sort of exploitation and get your care to you in a timely (well probably a long timely) fashion.
Note: The chart is possibly not complete as there seem to be several layers of pork missing.
