Andrew: you seem to be suggesting that within a discussion of profit rate
determination, constant circulating and constant fixed capital need to
both be positive since they are "always present in capitalism." Yet, workers'
consumption = 0 is *never* present in capitalism. Why can't you just
forget once and for all that v = 0 assumption? Yes, I know I'm beginning
to sound like a broken record (see the beginnings of the "assumptions,
assumptions, assumptions" thread a few months back). Let's instead develop
models where constant circulating capital > 0, constant fixed capital
> 0, and variable capital > 0.
