This is a complicated discussion, but for any given "technology" (i.e. set of available methods for producing every good/service in a society) and set of preferences among agents (e.g. households, firms) it is generally the case that there are many possible profit rates and wage schedules that allow for equilibrium. For a very formal an influential discussion of this, see Sraffa's "Production of Commodities by Means of Commodities".
