I see that with time, the class disparity is gonna increase a lot. Just look at the stats for the last 25 years.
Regarding Ivy League, I wonder if the Ivy League starts taking students with low GPA etc etc and see how successful their students are.
Personally, I don’t think the Ivy league makes students successful since most of these students are pre disposed to be successful anyway as they have strong work ethic evident from their high school grades/work. It’s a cycle which feeds itself.
