Boys do dangerous things like drinking and driving, hill jumping, speeding.
Heck, there was barely a time when, on back roads, that my motorcycle was traveling at less than 80 mph.
And you’re right, it’s the institutional (secular humanist) schooling system, and it’s gotten worse.
I think one reason it’s getting worse is that the conditions of schooling go on much longer in life than they once did. The prospect of “getting away” is much further off. And, of course, the increase in broken (or never formed) families is relevant, too; it’s just not universal.
