The simplest ‘fix’ would be for parents to pay for the education of their own brood.
Even better, would be to pay each teacher...kids more inclined to the arts? Pay for band, pottery, drawing, etc. Inclination to ‘hands-on’? Maybe shop, vo-tech. That’d really show how much sex-ed it needed, and better teachers would be sought out and as ‘on the hook’ as the parents for teaching (no more ‘passing ‘em just to get rid of the problem).
In my most totalitarian moments, I think kids that don’t make a certain GPA, cut up in class, ditch class, and so forth should be bussed out to the woods and made to thin forests all summer.
Hard labor has a way of teaching a kid what’s up, and it’s better than a summer of hanging out with hood rats, making babies, smoking weed, and drinking cough syrup.
