The kids already knew the right lesson. That you have to share but just enough that the legos don’t get taken away. That’s the correct lesson and the teacher tried to inject a bunch of social Justice power stuff into it
"What the teachers are doing is preparing the kids to defend themselves against the default politics in the world today, the politics of capitalism, of "might makes right" and "I've got mine". "
Oh please not more of this.
If you used the word 'capitalism' in teaching kids how to share, you're infected, you're part of the zombie army.
If the kids are not sharing, have them share in a few words and that's that.
If you write a treatise about it that uses words larger than the kids can even understand, you've decontextualized the situation and are spreading 'verbal covid'.
What the teachers are doing is preparing the kids to defend themselves against the default politics in the world today, the politics of capitalism, of "might makes right" and "I've got mine". Sure, you can scold them and tell them to share or the legos will be taken away, but by engaging them in dialogue you are allowing them to reach the conclusion on their own that sharing is best, and it'll be a stickier lesson for when they're grown and out in a world which teaches them that not sharing is best.
