?? parameter: ? Progressively accumulation interest,
                                   no answer except "confidence"
assumed: 100% saving of interest after all the very name "credit" says
if only a part of it is consumed,      that it is a matter of belief.
then an increasing proportion of ?
will go to rentiers!
But the wider problem reduced to this:
the interest would have to be paid out
of "wages" (incl. salaries etc)
Ultimately, however, the wages must come out
of production-
but this might be prod. of services,


or small scale production-
