assume credit is rationed by interest rate
assume there is only internal credit
assume no defaults
assume adjustments are only made to prices
not quantities
etc etc etc
thus might one launch
a just so story for the chattering herd
of course whatever the list of pre requisites
leave them strictly implicit
so the monks at the local econ con monastery
can chase each others tales and tails
endlessly providing
the necessary excavations of hidden assumptions
chime the terrors of tiny town
trigger the ceaseless gibber of toyland cross talk
