Not sure I'm buying it, but it's interesting.
If banks try to act like they are real estate companies and hold on to a huge inventory of foreclosed homes, they are likely to lose money big time, as those homes deteriorate and cannot compete with homes marketed by real estate companies with far more experience and expertise in this field.
But if teachers fail to educate children, they don't lose one dime, no matter how much those children and the country lose by their failure. If the schools waste precious time indoctrinating children, instead of educating them, that's the children's problem and the country's problem, but not the teachers' problem.
Sex indoctrination is just one of innumerable "exciting" and "innovative" self-indulgences of the schools. There is no bottom line test of what these boondoggles cost the children or the country.
Incidentally, conservatives who think that schools should be teaching "abstinence" miss the point completely. The schools have no expertise to be teaching sex at all. We should be happy if they ever develop the competence to teach math and English, so that our children can hold their own in international tests given to children in other countries.
