I'm less familiar with other countries' systems, of course, but, for instance, if I get ripped off for $15, it's hardly worth even taking a day off of work to go pursue that. But ripping off tens of thousands of people for $15 is hugely profitable, so there's a benefit to class action in that sense. I'm not sure how other countries approach that problem but would-be reformers here generally just want to make each person have to waste their time.
