TBH I think these guys who played into the scheme should lose their money as a lesson to what happens when you give your trust away to people who don't deserve it. But I'm just hardcore like that.
You don't sympathize?
I do, everyone makes mistakes, but a part of making mistakes is experiencing the effect of those mistakes; if they get their money back then the learning experience is lost and they'll wind up making the same mistake with the belief that they'll get their money back again. This is what allows ponzis and pyramids to occur at all: there's no more risk involved, or so they believe, until one of these schemers winds up succeeding with a lot more cash than he would've if everyone knew to avoid such schemes in the first place and to only deal with reputable businesses. Of course, the schemers do their best to hide that they're a scheme, but still, there's signs.
Losing sizable amounts of money is a traumatic experience, even if it's ultimately recovered. People don't just go "well, I lost $10k but since I got it back, let me throw it into the next shady investment"
So no, I disagree.
The PT Barnum "there's a sucker born every minute", if that's his quote, rings true. The people who get burned, again, even if they ultimately get their money back, aren't the ones piling into the next scam, but rather its a new generation that's also blinded by greed.
People are suckers, generally. Which, I think, is why we unfortunately need laws to protect them from the most predatory members of society. Probably won't go over well in this crowd, but it's still my opinion.
