I don’t know, a lot of them are for some ideological reason or need. And I just don’t mean religion but some sort of view about education or some perceived need they saw in education field that the state or municipal government wasn’t filling. Christian schools, Waldorf/Steiner education, international schools, providing education closer to home, filling in a need that the job market has. For those sort of reasons the profit angle might be not a very high on their list but rather they want to fill that need they think exists.

Of course since you can’t run a s school for profit that means there aren’t such schools so those even thinking of profit high on their list wouldn’t apply a permission to run a school to begin with.
