The "best" students, those most likely to be successful within the school and after school, become walking advertisements. They're also more likely to be happy alumni who donate to the school. I wonder what the data would show if you compared the money invested in admissions to that invested in alumni affairs & development, and how much is brought in by tuition and fees and how much is brought in as donations. From what I've seen, development is definitely an area that operates on the "you have to spend money to make money" principle.
