That's an interesting thought experiment. I think a lot of people would be receptive because there's a perception that public schools are failing a large segment of Americans (probably because they are). There would be curiosity about whether "Swedish educational models" could help. And there would be nativists protesting that this is an attempt to indoctrinate children with socialism and the New World Order. Almost certainly the teacher's union would be against it.

Probably not so different from the dynamic in Uganda.
