I'm not that convinced about most white middle class parents. 20 years ago when there was evenings of meet the teachers of your children. Often my wife and one or two other couples would be at these meetings. This continued from elementary to high school.
I will never forget what a good middle school teacher told us, when we asked how our children were doing.
He said great! He said that any student, who had parents who came on nights like this usually did well. In classes of 30 students per class, we and two other couples were in that classroom that night to talk about our children with their teachers.
Now, there is one elementary school where our sons attended that has the best teachers. Parents do anything to get their kids in this school. On parents's night at this school, parents have to park 2-4 blocks away and walk to the school to attend the parent/teacher conferences. My wife drives by another school coming home from work, and the parking lot is basically empty on these evenings.
