I had the misfortune of having to accompany a friend and his son to a level1 trauma care center in Luton in the UK. His son had passed out from binge drinking and got his stomach pumped for his efforts.
Whilst there the only people I saw were bleeding or seriously ill, they were quickly triaged and treated in order of need.
In a Houston emergency room you may see 3/4 of the people in no apparent distress waiting in the knowledge that they wont be refused treatment regardless their ability to pay.
There is no doubt reform is needed, on a lot of the system, but government takeover is not the answer.
