the link between loansharking and alcoholism.there is a new immigrant that doesn't speak the does not know what the terms mean. carol: i want to take you back to the birth of predatory lending. he writes about this. american moved west, the settlers preceded the banks. there were no organized banks out west of the ohio, all the way out to california. people got money wherever they could. supplyarks spring up to loans where conventional banks would not lend or had not yet gotten to. oliver: i guess that begs the question, you have lenders and sharks. but there is a gray area in between. in the book, how does he assess at what point you become a shark? >> one problem that abetted the loan sharks is states set a ceiling on lending rates, 6% or 7%. remember you have to take , inflation into account. if you had a fairly high inflation rate, 6% or 7% is especially for a loan with the carrying costs, and the processing was expensive. it was not high enough for the standard lenders to make any money, so they kind of left the field open.
