When you have 15 or 16 kids applying for every seat, you can afford to be picky. As an example, Harvard had around 35,000 kids apply for less than 1700 freshman seats. With a yield of over 80% of accepted students, Harvard can accept only about 2000 of those 35000. Yet, probably 10,000 or more of those students are fully qualified to succeed at Harvard. So, even among less-qualified sub-populations, there are plenty of fully-qualified candidates, because of the overabundance of qualified candidates generally.

Abut the same number of seats and 50000 plus apply yearly, they can and are very selective
