Honestly I think the majority of people in this thread are missing the point due to the fact that he named Walmart disregarding the fact that he said any other large place (meaning where people gather).
Emergency room healthcare is one of the most widely abused systems in the healthcare industry, simply because it is illegal for a hospital to not see you regardless of why you are there.
Have a migraine.. go to the emergency room they'll fix you up with some aspirin right away and can't force you to pay. Sprained your ankle.. Emergency room coming right up; forget about the guy with the knife sticking out his side or the poor kid just just broke 30% of the bones in his body due to a horrific car crash. They'll fix you right up.
Point is this; when people need emergency healthcare there is a long wait for it and an expensive fee; both directly related to the abuse of the system. I know first hand as I deal with a number of people with debilitating diseases that truly need emergency healthcare at times and have to wait upwards of 6-12 hours to be seen.
In addition to this it wastes hospital resources which if you've been to any emergency room you can attest that they seem to be short on said resources (again due to abuse of the system).
Where I live we are starting to put small "Ready" clinics inside of HEB. There you can be seen by a nurse or physician to see you for SMALL issues;
Also the video is way out of context
Here is the full video in it's entirety which makes the proposal of a clinic inside walmart much less loony sounding:
YouTube - John McCain on Health Care and Wal-Mart Clinics
Come on, you're all smart people here. Surely people can put 2+2 together and not jump on the bashing bandwagon when the video was obviously clipped to make him sound like a lunatic. Even in the original posted video you'll notice he says "if you have a cold". Not "if you're 5 seconds near death".
I have a number of friends that use the Ready Clinics here in town and they are great for the purpose that they serve.
I'm sure someone will bash me.. go for it.
I won't deny that McCain is stumbling over his words and sounds a little dumb, but I can connect the dots to see where he was going.
