Is this causal or coincidental? That the high school graduation rates, not to mention the percentages of those going on to attend and graduate from college, have not changed significantly from the seventies. And that the salaries of our middle and lower class workers have not risen noticeably during that same period?
In any case both trends merit some thought, some explanation. And, as long as we can’t explain either the one or the other, which is our present situation, we are free to say, either that earlier failures in school account for the increasingly low salaries among the working population, or that the low salaries, which in a growing number border on poverty levels, account for the failure for the children, living in these borderline situations, to succeed in school.
