"I don't agree with "poor" or "rich", black or white. I believe in expectations and its imposition to create a competitive drive in young children and adults."
That's part of it but not all of it. Whether you care to admit it or not: student to teacher ratio matters, quality of teachers matter, facilities and curriculum matter.
I went to a Catholic elementary school because that is what my parents had done. The teachers ther were a 50/50 mix of nuns and "regular" teachers who were hired as much for their religious faith and their teaching ability. There were no labs, there were no computers, there were no language classes, etc, etc, etc. A fair amount of class time was spent on religious intstruction. Did my parents expect me to do well? Sure. And everyone I was in school with was expected to learn too. Our parents were all paying extra just to send us to that school.
Then when I was in 6th grade, we moved to a snooty school district in the middle of a school year and I was to finish the year in the public middle school and then register at the Catholic school the next year - if I wanted. The new school gave me some standardized tests and I was placed in advanced math classes and pretty much regular everything else. I had no idea what the hell was going on in that math class for the first few months. And I was behind in history and science. I took art, drafting, computer, home ec, health and language classes for the first time. By the end of that year my parents stopped talking about the Catholic school altogether and by the time I went to high school I had caught up to and passed alot of the kids who were ahead of me in all those other subjects.
Same kid, same parents, same expectations but entirely different experience at the better school. Schools with less resources or, in the case of the one I was attended originally, misplace priorities are going to provide a lesser education. That's just the way it is.
