NUMBERS DON’T LIE: You may have noticed big-city public school students who were encouraged to protest capitalism on May Day. I did and it prompted me to look at the numbers that tell the story of how public education is a national disgrace. One might expect school districts with the highest per-pupil and teacher salary spending to be doing the best job of preparing our kids for productive, rewarding careers. One doing that would get it exactly wrong, as I report today on The Washington Stand.
