No, the lawyer's job in a class action is to hold the someone accountable to prevent recurrences. They did a job, so they ought to be paid.

If some company habitually breaks the law and causes damages to a large group of people you can either pray that the Attorney General takes the case (but they won't, they want to advance their political career) or a law firm will take the case out of pure financial interest. I'll go with the law firm.
