Yep, and my reason for introducing a rising population is that such is the
fact--though the rise follows a logistic path rather than exponential, and
there does appear to be a relationship between income levels and position on
the logistic curve.
My single sector stuff (the Goodwin/Minsky paper) has a rising population,
of course--and the dynamic between capital accumulation and employment
includes a rising population as well as technical change.
