As an individual with first hand experience, it works, but there are major down sides. Everything is SLOW. For example, I am a baseball pitcher, and when I was 14, I threw a pitch and my elbow exploded. It became swollen and I could barely move it. I went to my doctor and after getting the x-rays back, an MRI was ordered to determine soft tissue damage. Everything was going well, I hadn't paid a dime for the care I had received, and I wouldn't pay for the MRI either......except my appointment was in 13months. THIRTEEN FLIPPIN months to get an MRI?
You get the idea. It is great if you have minor problems that can be taken care of qucikly and relatively cheaply. If you ever have serious complications or trouble, you are in it for the long haul.
I ended up driving down the the states and paying for a MRI at a private clinic. Social healthcare is just to damn slow.
