Medical in the US cost more but there is "more" available. If I were at my doctors office right now (3:13 Central time) and he felt I needed a MRI, I could have one before 5:00. I've often heard that in a non-emergency situation there can be weeks of waiting to get an MRI in some European countries. I have also seen a comment from a guy in the UK who had to have his arm re-broken for a cast to be put on because it had already started to heal crooked while waiting several days. A few years ago I spent some time digging through official government reports on healthcare in several (well limited to English speaking) countries and found things like >8 hour wait times for emergency services, >30 day waits (in some places) for some non-emergency services, etc. Yes, we pay more, but the flip side of that is faster access even in non-critical situations. In my case in February, I was at the doctor at 11:00AM on a Friday, MRI at about 1:30PM, and by 4:00PM I was scheduling surgery for Monday for gallbladder removal. I could have probably waited, my discomfort was relatively mild at that point, but I didn't have to.
So you have some anecdotes about bad service. In reality, we have studies that conclusively show that US care is both more expensive and less effective.
