Don't you find it funny that an org such as the church is a non-profit? I mean, sure, it has not stakeholders, but woah boy their members get decent salaries. I guess I should incorporate a non-profit.
That really depends on the denomination.
Sure, there are pastors of evangelical megachurches flying around in private jets.
On the other hand, other religious groups often have quite poorly paid clergy. I remembering hearing about an Eastern Orthodox parish, where after paying for the building, utilities, etc, the parish didn't have any money left to pay the priest. So he is working a full-time secular job, his wife works part-time (as well as looking after the kids), and the priest does all his religious duties after work and on weekends. (The plan was to convert enough people to Eastern Orthodoxy that the parish could fund the priest's salary and he could quit his secular job; hasn't happened yet, who knows if it ever will.)
One of my former work colleagues was a Protestant minister. His church was too poor to pay him anything. He worked for Oracle during the week, and ran church services for free on the weekend.
A lot of religious denominations are struggling with ageing congregations and declining membership. Even if there is sometimes still a lot of money at headquarters, when you get to the periphery of shrinking local congregations things are often very frugal.
