I agree with the part that some are not qualified. I would amend the latter statement by saying college should challenge only those who are motivated to succeed. A high IQ is not necessarily needed to succeed in life, or college. That having been said, many blacks and latinos are simply not motivated and should not attend college. Call me racist, but I've observed this as a fact throughout my life. My daughters finished their university curriculum and graduated by the time they were 21. They told me college was so dumbed down for minorities that you could show up simply breathing and graduate. An exaggeration, yes, but many minorities were there to party or simply not motivated and wasting resources that were denied to others.
You are not racist, you are telling the truth.
