While I don't agree with everything this article says, this is the money quote: "If professionals who benefit from the economies of scale cannot reasonably be expected to provide me with a stable retirement without outside intervention, how can I be expected to do that for myself?"

And is spot on IMO. Whatever else is going on, we as a society are doing poorly at this particular type of specialization. We have done insufficient incentive engineering to make sure people don't regularly get scammed. It is not a solved problem, it is not an easy problem. But it looks like we aren't even working towards a solution right now.
