<p>Didn't read the rest of the posts but replying to the topic name, if American student population grows to be huge, then there is no need to increase student intake at top schools.</p>
<p>Merely, there would just be a higher number of "top schools" to be identified. For example, the lower tier from 25-50 will become more selective and therefore be "top schools" since the old tier 1 (let's say 1-25) are no longer to accept so many qualified students. </p>
<p>You can actually see this trend now, with schools like George Washington University becoming more selective and its peer schools following suit.</p>
