Like other industries, this is full of vested interests, protecting current doctors and keeping scarcity in the profession. HK doctors do in general have very high quality, but they are also among the best paid in the world. This kind of protection and management of keeping the pool of new students low, is actually common in many other countries. Therefore students in most countries needs perfect test scores to even apply. I always found it so strange that politicians allow this to go on in so many counties. So many want to study to be doctors, but so few are allowed..
