Phil:

Then ratio of the real to the absolute price systems is equal 1 + the ratio of
aggregate profits to aggregate wages. So real prices and wages are bigger
numbers than absolute prices and wages. Agreed, wages are part of value added.
But just as the mean hourly real wage is 1, so the mean rate of absolute money
value added (per hour of labour time worked) is 1.  This pretty certainly means
that the mean natural real wage rate is 1.

I don't think the ratio of actual real wages to natural real wages says any
thing about exploitation. If some actual rate was very much greater than the
natural rate, that might indicate unproductive labour.  It would certainly
indicate a problem of some sort.
