I would tend to disagree about civil litigation being that much work, because it takes far less effort than other approaches when measured by effectiveness. I’ve had situations where I’ve reported crimes to the authorities. Most of the time these reports go ignored. In one major instance they refused to even take a police report. I’ve put cases together will all the evidence needed for a conviction, and only once did they actually arrest the person (and even then adjudication was withheld). So yeah, leaving it up to the government is less work, but there’s a good chance nothing will happen (particularly if they’re not politically aligned on the issue / it would offend donors / etc.). Then when there is a “major” enforcement, it’s usually a slap on the wrist and no the victims get less than they would have from a class action.
