Yeah, trapping wolves and yote is definitely nowhere near being financially lucrative (at least in comparison to the past). The people I know that do it take a few every year to help out the moose and share the pelt with friends and family, and to keep their trap line active. I think a lot of people have a misconception that there's hordes of people out in the bush chasing after every wolf in sight. To try and infringe on a sportsman's right to sustainably trap and hunt predator animals simply because you don't like it is seriously off, in my opinion.
I'm sure if we cancelled every bass and walleye tournament in Ontario, you would see a notable increase in fishing quality on many popular cottage lakes in a few short years, but I am not about to tell a tournament angler that he/she is wrong in doing so.
