Sounds like a another way to continue the trend of child-proofing the world, so that "everyone can learn at their own pace." Right. What these people are unable, or unwilling, to recognize is that the world meets nobody half-way. We either work hard at learning how to succeed and survive, or we fail hard.
"Unschooling" is just another way for lazy, stupid parents to coddle their children toward a lifetime of failure, mediocrity and narcissism. In 20 years, when these kids turn out to be useless tools who are unable to work for what they want or even support themselves, they will turn around and blame the government and you and me, for not doing enough to help them. (And no doubt they will do the complaining in a petulant, entitled tone that makes you want to punch them hard in the mouth.) Is this what we, as a society, want?
Yes, let's have more unschooling! Looks like a winning strategy to me.
