This is just another nail in the coffin of public schooling. We've watered down the high school diploma so much that 20% of high school graduates are functionally illiterate. Based on the increasing requirements for bachelor's degrees where it doesn't seem to make sense on the surface, it seems employers have caught on to how meaningless it is.
Who is “we”? Public schools at the local level in the US are very diverse. If you have the money you can find public school systems as good as Ivy League colleges, with a self-selected peer population of students with highly engaged parents.
