I'm certainly no fan of this DeVos billionaire, but I do not see the harm in having her come and getting a close look at Ontario's very successful public school system. If another American comes away impressed with the way we do things here, maybe we'll influence how the US evolves in the future. We won't change her mind, but her successor might do more. Teachers' unions are dumb to criticize the visit (and I'm talking as a union member). How close-minded are our educators anyway? It's troubling.
