I don’t know how much my kids’ teachers make, but they do get free tuition for their kids if they attend the school. What I do know is that last year, they were not given a pay raise due to the budget shortfall the school had. Not one teacher left or complained (we have several teachers who have been there for 25+ years, including Sr. Mary, the librarian). That told me everything I needed to know about the dedication they had to their students.
At my kids’ school a few years ago, they did away with teacher’s kids getting a tuition break. They couldn’t afford it. They haven’t had raises for a few years.
