It’s a description of the economics of a corporation. If they have so much in revenues and so much in non wage costs the difference either goes to wages or profit. If revenues drop either profits will drop or wage costs will. In the very long run your pay will tend towards your productivity but ease of replacibility will also play a role among other things. Sculptors and aerospace engineers are both highly skilled but there are many more jobs for the second than the first so they get paid more. In the long run it is almost a rule that if gpm drops wages will. Profits could also drop. The mix of compensation could change. They could keep wages the same but fire the least productive staff so the wage bill drops but the remaining workers do more work.
