I think Harvard’s acceptance rate would drop below 5% or whatever it is now, frustrating even more applicants.
Part of it is PR and Harvard could fix that by mailing posters or whatever to every high school in the country, targeting poorer ones, making sure kids DO know that.
But I think the larger problem there is that poor kids tend not to have Harvard-level stats, in part because our schools are not good in areas where most poor students live.
