One thing that I never understood about the US medical education is the requirement of the bachelor's degree (pre-med) before applying for most med schools. In my home country and many others, you can directly apply to med school. Now that the college costs are quite considerably expensive, four-additional year of college studies simply adds to the cost of becoming a doctor and therefore, the newly minted doctors expect to make a lot of money. This pre-med education requirement adds unnecessary, in my opinion, burden not only to wannabe-doctors, but also to the medical system (create scarcity of doctors to say the least).
