I have friends/acquaintances who are "Buddhist priests" in Zen traditions outside of Japan. They are semi-householder-ish, definitely not monks. However, they dedicate their lives to Buddhist service. They don't have children, but some are married or in relationships, mostly together with other "serious practitioners." They very definitely are not billionaires or CEOs -- and I am a little surprised at this story, which could definitely be clearer about what his priesthood actually involves.

Possibly interesting article by an American Zen priest:
