I see things in terms of a sharecropping analogy, feudal lords (corrupted government) allow the scammers to harvest the crop (victims) for a share of the proceeds. We cannot fix people to the point they are un-scammable and there does not exist a democratic force strong enough to fix the government. Almost all ads I’ve ever seen are for obvious scams, especially on twitter. You’d think the richest guy in history (possibly?) could afford not to allow industrial exploitation of his users but apparently not.
You have gambling sites and binary auction scams that have a turnover that includes a significant percentage of suicides. I wish we had a democracy that could prevent this but we do not. While many of us here may be smart enough to avoid falling victim to these scams we have family members that we care about who are not so this still indirectly costs us wealth.
