on interest accruing that penalises payments that fail to meet a time deadline or a premium amount a company can very quickly make the money back that they lent out while still having the individual held under crippling debt, if i use a credit card foolishly and put myself into 2500$ debt, and over time receive a number of fees due to my late payments, my 2500$ debt can rise to 5000$ effortlessly, at this point if i pay the bank 4000$, they made 1500$ off me already, then they decide to sell the remaining 1000$ for 1/12 its worth the original lender has been given 4083$ for an original 2500$ loan, and now the credit adjuster or whoever bought the debt could make 917$ by collecting the 1000$ i'd like to see statistics on how much an original debt was, how much has been paid into it, and how much it sold for then we can discuss potential for 'total loss' i wonder if you went to the lender and offered to pay your debt back at 1/12 its cost if they would sell the rights to your own debt to you?
