Unfortunately, there is more truth to it than we care to admit as an American. Most of the graduates out of high school the last 8-10 years are unable to read at a 8th grade level.
This down hill spiral started back in the mid 60's when the US Supreme Court changed the definition of "church". , which was an unconstitutional act, but no one called them on it.,and it stood. Since the effects of that took place, the S>A>T> scores in US high schools has DROPPED over 80 points, but the home schooled, and Christian schools have not dropped at all, because they maintained God in their life, and education.
There are alot of "rich folks kids" that are very uneducated, doesn't pertain just to the poor folk.
