I agree that public school should not leave any kids behind. I also want my taxes to be raised to fund a higher-level education for kids who may find it useful, even if it's only a small percentage of kids.
Sure but that's only fair if the assumed skills at higher levels are attainable for an average person that went to a public school.
BTW "no child left behind" isn't practical, there are people who can't learn basic stuff no matter how hard you try. But "less than X% kids left behind" is for some low value of X.
