put in a nice new beautiful mall in SLC or spare millions of dollars to the friggin U of U for a new law building i think they can expand enrollment at BYU. I would argue that it might even be in their best interest to do so. I know that they think BYU Idaho was the solution and maybe it was to a degree, but expanding the flagship school would probably help ensure a larger tithing paying donor base that would also increase the likelihood of donations to the actual school.
The argument I have seen is that keeping enrollment lower keeps BYU's academic profile higher, not that it is too expensive to expand. I would argue that BYU will never achieve Elite academic status as a primarily undergrad religious school without a medical school. We just dont check off enough boxes in that regard so why care about what Stanford or UC Berkeley or Yale or... you name it in academia think.
The students are seen as hard workers and expanding enrollment shouldnt change that. Yes our ranking may take a hit because we arent as exclusive but more students who are passionate about the school (passion is in part instilled by the love of the athletic programs) the more passionate donors we will have in the future.
