Well I think it's only natural we favor what we are familiar with and yes, I think if all things were equal I would prefer an American doctor, but the percentage of American to foreign doctors is steadily declining- especially in the south. And good luck finding any like those on TV. Dr.Welby is dead.
And I'll tell you something else, being the hypochondriac I am, I subscribe to a daily email service that sends me news of the latest medical research studies, and most of these are now done outside the US. I think this is another sign that we are falling behind in the medical field.
I was watching a show on PBS last night and they mention something that I had noticed myself- there are no more home chemistry sets for kids. When I was a kid these were popular items- I had several over the years. Now however they are considered "too dangerous". What is to inspire future doctors and scientists and engineers today?
