I am not familiar with the term “ open access university “ and they didn’t really explain the term. I know Georgetown is a private school.
Here’s an idea : instead of telling other people why you consider something to be a problem ( broadly racially categorized unequal outcomes ) and asking for government money to fix it, do what you are suggesting at your own institution first with your own money and then convince people with your empirical results.
I also tend to question the statistics they provided. For instance, how do the graduation rates of American versus nonAmerican nowhite students compare ? And what are the statistics for those first in their family to attend college versus students from multigenerational college families ?
