And indeed there were people arguing against high school education across the board for everyone: not all students needed to go to high school, they were better served not learning any history or mathematics or science or civics or ethics or English or geography or about the modern world and instead going to an apprenticeship in a trade at 12 or 13, where they would toil for the rest of their lives. The few elites could go to high school and study more lofty topics required to make serious decisions, since they were, after all, destined by virtue of the fortunes of their birth to be the rulers and decision makers in society.

But high school for all is generally considered by everyone to be a Good Thing and having a more educated populace is good for everyone: jobs change, times change, and generally educated, intellectually flexible citizens are better able to adapt with the times, vote intelligently, be part of modern communities, etc. You can go to a trade school after high school.

We've come along far enough it's time to recognize that high school is no longer good enough as a general education, and that's a good thing: a college education where students study philosopy, history, science, mathematics is now the basic standard for an educated citizen and we should provide it to them regardless of how wealthy their parents are or how well they take IQ tests.
