I'm happy to invest in a relationship with recruiters who will be around for a while. But I get the impression that most recruiters have only short stints in that work.
P.S. I would like to give credit to one recruiter though: Markus Edmunds. He'd been recruiting for a particular technical specialty a year or two ago. He really got to know my preferences and strengths, and never ghosted me when individual companies passed on my resume. I know that's indistinguishable from him acting in enlightened self-interest, but it was still a productive relationship.
