Not necessarily. I rent my house, and the housing corporation who I rent from are not rent seekers, they provide a service to me which I'm happy with, and which they invest in.

They could've bought up the land and house and not improved it at all and depend on the housing crisis deepening for increased resell profit- but they did not do so, they maintained this house I'm in and ensured me and future tenants can continue enjoying this place. That's not rent seeking.
