I believe that bearing costs is the reason why a person prefers one country over another. Good medical care will not be free, and then you may not be able to afford it, especially for individuals in the middle and poor classes. There are also consequences after the operation, such as care in the first months, medicines and other costs.
Also, some countries are better in certain disciplines, this chart may give you better information, although I am surprised at the reason for choosing Mexico, perhaps because of the flight costs)
Wait, what? I can't see The United States on that list. Does that mean that one of the most powerful nations and a very developed country spends less than 6.3% of its GDP on its healthcare systems? That's pretty surprising, and no wonder why people from there travel to neighboring countries for their medical necessities.Also, some countries are better in certain disciplines, this chart may give you better information, although I am surprised at the reason for choosing Mexico, perhaps because of the flight costs)
And I believe that it happens in almost every country where the lower classes who can at least travel go somewhere else to get proper treatment at less cost. Governments need to take good care of their healthcare systems more than they do right now.
