“I think the writer’s points are excellent, though he is obviously not talking to everyone. If you know you are going to be in chinuch, and you won’t need a degree of any sort AND your rebbi tells you to sit and learn all day, that’s one thing.”
Wrong. Those going into chinuch needs the degrees even more, so that the schools they teach in will pay them decently. Get both a Smicha (Yoreh Yoreh or better) and a Masters if you want a serious Avodas Kodesh career. I have seen a school’s salary schedule and credentials play a big part in setting salary.
