To need-blind admissions...
I would have zero problem with this if they demanded the same standards of academic merit and educability from the students that I will be one day subsidizing. That way my DD will have a reasonable chance of being able bounce ideas etc off of smart people and the academic merit of the institution would not be compromised.
I fully understand that low SES people can be smart - I grew up as one but it galls me to see standards being applied unevenly across race so that better qualified applicants are missing scholarships because they are the wrong race/gender/colour/sexual orientation etc.
I personally think that extra support staff needed for marginal students that shouldn't even be at university and self indulgent pseudo-intellectual fantasies like [insert trendy social hypochondria name du jour here] studies that have 3 students are also ramping up 'tuition' costs here.
