Not fair! They can simply look harder. How can it be said with a straight face that there are zero qualified candidates in those example states? Preposterous. It just takes time to find them.
Wyoming has about 580 thousand total population, and no prep schools comparable to the East Coast ones. Its not simply raw intellectual ability. The most qulualified student in each year from that state will most likely find an Ivy League overwhelming. If each such school wants at least one man, one woman from there, it's not going to work.
