It is my impression that the concept of public (in the American sense) school for all was a giant leap in development, an experiment, let's say. We could also say the experiment has failed; at least, in some cities in the U.S. conditions in the public schools are dangerous to both faculty and student body.

Good or bad, maybe we are in the process of going back to small-cell schools, schools where we can control the student/teacher ratio, where we can be responsive to the needs of individuals and where the schools are community based? It is certainly true that secular charter schools are already omnipresent.

I should imagine that if we are indeed in that process, then same-sex schooling will be just another option.
