I suppose there's an argument to be made that attorneys make too much money in general (though like most anything fees for legal services are largely determined by the market). It's a little silly to suggest they make too much money off of litigation such as this one, or have some sort of "conflict of interest" (?). Litigation--particularly complex litigation such as this--is extremely time-consuming and expensive, requiring the work of numerous individuals for hundreds if not thousands of hours. And the fees are going to be a minority percentage of the overall judgment. The purpose of a class action isn't necessarily to make whole every conceivable class member, but (among other reasons) to aggregate small losses and/or to force a change in behavior through the collective financial penalty. It's surely not a perfect system--nothing is--though what is a viable alternative.
And of course, you have an option to opt-out and sue on your own. Generally, obtaining recovery through suit requires a fair amount of effort and expense.
