Why UMCP use CSS Profile?

It is a good, competitive school; and it’s located beside the capital. With that reputation, why doesn’t it try to award students a better financial package by introducing the CSS Profile. This would allow the school’s own money to be disburse to students.
I live in Maryland andI in the south there are many low-income families, while in the north are very wealthy families and good schools. Almost everyone in my school or county has inspirations to attend UMCP.
I post this thread because I have saw some bad financial statistics at UMCP.
