Here are some quotes from an excellent WSJ article about struggling Catholic schools. The emphases are mine.
The bishop and his flock in Wichita, Kan., embraced a stewardship model that calls upon all parishioners to give 8% of their gross income, which allows the diocese to make all its Catholic schools tuition free.
“We can’t wait for vouchers, and we can’t look to the old model of relying on our pastors and bishops to come up with the money and answers,” says Mr. Busch. “If we want Catholic schools for our children and our society, we have to adopt new models that let us compete.”
