In my region ( USA), ordinary people simply don’t have the resources for individual lawsuits like this.
It would have to be a well connected or monied individual to have any chance. Or the situation is so egregious and documented enough, that a law firm thinks it can make money, by taking most of the winnings from the victims
I see this in my own field as patent trolls.
Not ordinary people, and relatively rare per capita; but the population is big enough to have many parasites; or a very proficient few based on what they practice.
My life would be easier professionally if the top ten patent trolls went out of business nationally
