I mean, you basically answered your own question. In the existing situation, the lawyers take not only 30%, but additionally they take 'fees and expenses' on top of that. (Because apparently 20 million dollars is not adequate?) And it is all merely based upon what the airlines are actually willing to pay. Presumably, they are still better off than if they had not partaken in the illegal activity at all. The lawyers are basically just saying that they are willing to look the other way so long as they get their share. Compare that to a system where a stronger regulatory body were involved where they could demand restitution directly to the individuals at the rate to which they (the regulator, rather than the airline) believe the airline profited. Even if it is a minor amount per person, it would ensure that each individual is in a similar place they would have been had the illegal activity not occurred, and the company has to go through all of the additional expense of attempting to recompense all of those individuals. Just seems fairer all around.
