FYI private schools are not immune to these problems. The administration of some private schools choose to have similar policies (accept late work indefinitely, minimum grade of 50%, etc) at their school.
The main advantage private schools have is they an expel problem students and let the public schools try to handle them.
It ends up selecting for people who are more transient and have less experience, who haven't gotten the better Public school job yet.

They theoretically have more control over expulsions, but whether or not they use it really depends on the school.
