Help people complete the destruction of their marriage.
$$: Some charge on a sliding scale, depending on the income of the suffering couple. While some marriage counselors may be MD psychiatrists or PhD psychologists, a fair amount simply have degrees in social work or counseling, and they get paid okay, too.
The upside: You're single!
The downside: It's like working in a coal mine in which the canary keels over and dies every day.
The dark side: You get a large dog and move into a small houseboat on the marina.
