I used that as merely an example, but was afraid of it taking over the conversation. Sure nothing's perfect, but I'll share one of my experiences. Had the misfortune of cutting up one knee in Greece, one in California a few years earlier. Got the same great care in both places, a few hours in the hospital, some bandages, and antibiotics. Bill in Greece $50, bill in California $1600. Bill collectors showed up in CA to get paid a second time.

You also seem to be taking the position that, since living in a place for a short time does not give perfect insight, that it is not valuable. I would disagree.
