The difference is that if you have a non uniform rate of profit
1. You can choose the case where it is a null transform - which is
certainly no less unlikely,
than the uniform profit rate.
2. If it is not either the null transform or the uniform profit rate you
are providing a whole
lot of new variables which can be set to whatever you actually
observe the profits and
market prices to be. At this point the theory no longer has any
predictive ability ( there
is no economy of information in comparing the theory with the actual
observed data).
Thus it is no longer a theory, merely a record of observed data.
A scientific theory must be more concise than the data it purports to
explain, if you introduce
as many free variables as the market prices, it becomes vacuous.
