According to "The New York Times," the United States has the best doctors in the world. This is mainly because doctors in the United States earn more money than anywhere else.
The United States functions as a "talent vacuum" within the context of the world economy. Simply stated, the United States funnels the best and brightest from around the world because it can offer the highest paying jobs and best living conditions. This ensures that the quality of the U.S. health care system is the highest in the world.
Furthermore, many countries are actually suffering from the talent loss, as they cannot compete with the United States in terms of incentives. It is especially prevalent in poor countries, where doctors, whose work is vital, earn much less despite the need..
This not only applies to doctors and the rest of the medical field but to all professions. For example, many of the best athletes in the world decide it is more fruitful to live and work in the United States than in their native countries, even if that means less fame. The NBA is an apt example of this phenomenon, as it is a cosmopolitan league with players hailing from all around the globe.
