A different take: I met an Argentine doctor just yesterday in Valencia who, until a few years ago, had a very successful clinic in Rosario. After a group burst in to rob the clinic, he relocated. He said, "I had four hours with a gun to my head to decide that I had had enough."
I know three other docs in Spain who left ARG for various reasons, but all are happy for a saner, more relaxed work environment. They typically don't get rich in Spain, but enjoy a decent, steady income and perks of the job.
