The SSPX schools do not prepare the boys to be working men. They focus on the liberal arts and not math, sciences, business, or blue collar positions. No wonder they say the young men are not ready for marriage. With the type of schooling they receive from the SSPX, they will NEVER be ready for any work but teaching and the priesthood ( teachers and priests that do not know how to use a screw driver!).
They might as well neuter the young men, they don't educate them to be capable of supporting anyone, but maybe themselves.
