If everyone stops paying back the loan sharks... Refusing to pay the "vig" which has now become about 90% of the total 'loan' value ... the Sharks will not have anywhere near enough enforcers to collect on ANY of their loans.  The LOANS are bogus vigorish machines that build nothing but debt.  When the medium of exchange,  itself becomes a PRODUCT,  the world becomes a financial fantasy land,  where nothing is properly valued. Screw the bankers.   Screw them hard and fast.  Then discard them like refuse.
