Not sure I agree with that. I’ll take an unexpected five bucks because of Red Bull’s false advertising that some ingredient doesn’t have literal energy (calories) to it. I wouldn’t start my own lawsuit over it, which may or may not be as successful. More importantly, every class action notice I’ve ever gotten had instructions to opt out and initiate my own legal action if I so choose. Also, if we’re talking about a class that includes thousands/millions of people, there are only so many lawyers involved in whatever specialty.

Tl;dr class actions penalize companies on behalf of those who wouldn’t realistically file their own lawsuit while still allowing those who would.
