You have a point; I was just saying that regardless of what one learns in college it is much more important that they learned little in the 12 years before (and not always due to the teachers).
It seems to me that the breakdown of the family has contributed to poor performance in public schools. When I went to grade school (about 30 kids in a rural setting) I believe all my classmates had both parents at home. (Now we are looking at only 59% countrywide). When you think of how disproportionally disruptive single parent boys are, it is no wonder public schools have gotten worse. It seems to me the universities should have done a better job about raising concerns about the impact of single parent homes on education.
