For example, let's say Bank of America (motto: Give us your money and fvck off, prole) was managing your house mortgage. You send in your monthly payment. You send in a little extra and it's applied to the principal straight away, recasting the loan balance and interest. Yay, getting ahead! Saving interest costs!
Only BoA wasn't doing that. They were keeping the extra payment money and applying it at the end of the month. They get extra money (& interest on it) for 1-30 days, and you pay 1-30 days more interest each month.
But someone noticed and sued them in a class action suit. I, along with thousands of other people around the world who were cheated by BoA, was part of the class action. The suit was settled for $65 million. After lawyers expenses and fees and class administrators fees (more lawyers) of $48 million, I got my check today.
I shall bank my $0.91 cheque of justice just soon as I can.
Oh, the amount BoA made from the fraud? Conservative calculations put it at $106 million. :-/
