The social dynamics can get really ugly when the m/f ration hits a tipping point, generally thought to be around 60%.
The focus on white males is because the system does everything it can to get "males of color" into college (well, everything but competently teach them the 3Rs, at least in the US with Dick and Jane and Their Running Dog Spot (Whole Word nonsense, phrase coined by Jerry Pournelle, who's wife's career was teaching the hardest cases how to read)).
I went to a 62%/38% female/male ratio, and social dynamics were alright. A lot of girls kept their hometown bf. (they had to), lots of parties, and getting laid was easier.
Now I had a close friend that went to a 70%/30% guys/girls school, and the atmosphere was definetly different. Things were more boring, nobody was getting laid, and the few women that where there were acting like they were walking over water.
People were more concentrated in studying than having fun (parties with only dudes, get boring pretty fast).
I know I am overgeneralizing, but things were ok.
Now if the ratio gets even worse, then who knows. Girls/women will have to date somebody that makes less then them or that has lower education level.
To a certain degree, that is what currently educated black females are facing.
