Hmmm...it depends.
I'm aware of a mega-church in the Midwest that is "hiring" people to evangelize and spread the word about their church. They charge their "employees" thousands of dollars to take classes that they are told are required to advance into the position. They're not paid anything and are taught that it's a sin to make more than a "living wage," (i.e. what they are able to raise for themselves.)
It all sounds like a big scam to me. Just my opinion. And it sounds like they're attracting mostly young people, just out of college.
