In class-action lawsuits the threat of astronomical liability drives many defendants to settle — even if the plaintiffs’ chances of success are negligible. But because there’s only so much money that defendants are willing to spend, such nuisance lawsuits often lead to settlements where the attorneys get more than their fair share. It works like a formula: The plaintiffs’ attorneys and the few named representative plaintiffs divvy up the entire cash proceeds, leaving the remainder of the class with a potpourri of worthless window dressing.
