The rest of your comment is a perfectly valid way of looking at things, so I'm not going to contest it. I think my comment stands and you have a different take, which is totally fine. We don't have to agree. But I did note this section:
>Fwiw, class actions of this type have been popular mostly in one country and only since the sixties.
I presume you're speaking of the US, but just a month ago (went into effect June 25th) the EU opened up and simplified their class action scheme ('Directive on Representative Actions') to make it simpler and easier to file class action suits and largely remove borders and jurisdiction squabbles from the discussion. This US style system was set up specifically because it better protects consumers.
Quoting from the EU themselves:
>However, the consumers affected may feel powerless and hesitate to take legal actions. They might be confronted to obstacles such as the uncertainty about their rights or about which procedural mechanisms are available, psychological reluctance to take action or the negative balance of the expected costs relative to the benefits of the individual action. Collective redress mechanisms, such as the one provided by Directive (EU) 2020/1828 are therefore needed to overcome the obstacles faced by consumers in individual actions.
