My father in law was a Protestant minister, my BIL is a retired minister and we’re pretty active in the church. For a good sized congregation that is in or near a big city and financially stable, we can easily get 75-100 applicants. The salary is decent, good benefits, pension. Being in a metro area means your trailing spouse can find a job. 50 years ago, your mainline Protestant pastor was a white male with a wife who helped out at church. Now, you don’t have to be male or straight or white, so the applicant pool is much larger- it’s very hard to get into seminary and expensive to boot. 40 years ago, our church staff was a full time minister, and full time or 3/4 time assistant that was paid or partially paid by the National church, church secretary, organist/director of music and a janitor. Now we have one full time minister, church secretary and director of music ( part time) and janitorial is contracted out. Our minister makes about $70,000 plus housing. I can see in 5 years, we will not be able to afford a full time clergy as church attendance dwindles. We have 3 churches of our denomination in a 3 mile radius and one is supported by a wealthy older woman who pays most of the minister’s salary.
In a rural area, many places are two or three point parishes where one minister drives from church to church. It’s hard to get someone to come because there are no job opportunities for a spouse ( although with more people working at home- maybe this is changing).
