Salaries are so low because they get their housing “free”.
Their housing in most cases today is not “free”. Most protestant Christian churches no longer provide a church owned “parsonage” for the minister to live in. Ministers buy or rent a home. The housing allowance is only whatever the congregation agrees to provide.
Okay, then ministers get double whopping deductions—mortgage AND housing.
No matter, it should all be taxed just like everyone else’s income—housing allowance or otherwise.
