There is only so much space to build libraries on school campuses. Plus building anything would cost way more than 6.5 million. More like 30-50 million. Instead they should offer to fund collage scholarships (eg minimum 5 million “contribution”, limited to two donations/students per year) and see if the schools take that in exchange for admittance. I guess it would be a pretty blatant bribe though, more so than building a library.
