>In a good legal system many small claims should be bought and then somebody could sue the company for money. This would be a superior version of a class action lawsuit. A version that is actually practical and would scale.
When you can buy and sell a legal action like that it strikes me as a super bad idea. Wouldn't there be some legal equivalent of the patent trolls who today purchase outdated patents and then go around filing nuisance suits based on them?
If you want to sue CVS for selling you fake aloe go ahead, it costs less than $100 to file a small claims case in my state and CVS will very likely settle with you outside of court because it's cheaper than sending someone to court to defend the company.
This exists, it's called small claims court.
