In the end, the people pay the money, and the lawyers profit. Any settlement from the gov't or banks will be paid by the taxpayers or the clients of the bank.
Why anyone thinks that this is anything other than a money-making plan by the lawyers is beyond me. Let's assume there's a settlement - where does the money come from, and where does it go?
The settlement will be a coupon, voucher or discount for the people the lawyers are representing and of course full legal fees paid in cash.
