I agree with this approach.
I believe the thinking was that America is producing too many teachers who know how to teach but don’t know anything else. They then use the degrees to teach ideologies rather than math, science, history, etc.
Another nice thing about Hillsdale is that parents can know that their kids are in a safe place without a lot of partying going on. Hillsdale is a small rural farm community and big parties aren’t going to be tolerated. They are college kids and there are some parties but they tend to be small quiet affairs.
