You have perfectly described the education-social welfare-complex. The whole rotten system employee millions of people.
One of the major reasons that so few churches run private schools is:
1) They minister's spouse works for the government schools.
2) In most counties the government school district is the largest single employer with the largest payroll in the county! No other business comes close. Add to that the vendors to the schools and their employees. Even my dentist and his 5 employees depend on government school dental insurance funding a major portion of his practice. So?....What minister is going to bite the hand putting money in the collection plate.
That is why the life of leisure guaranteed the welfarians requires them to breed; they produce clients for the education-social welfare complex, and are “paid” to do so...for 50 years it has been the chosen “career” of many.
