Yup, and this is essential.
The failure mechanic is that if you're successful, there will be a number of people who don't pass the 'vetting' but they want to participate. That demand will be met by people who don't do vetting, or choose to interpret vetting in a way that allows this person to participate.
A lot of the bad mortgages that were written in the real estate bubble were fraudulent, the "good" mortgage companies took care to insure that their customers could afford a mortgage and would be reasonably able to pay it back. The people who didn't qualify weren't served by them. Instead they were served by people who were less scrupulous.
This is the conversation we need to be on the look out for;
"Those guys turned you down because the rich folks don't want people like you getting in on this sort of deal and suddenly becoming rich like them, they are trying to keep you out by setting bars that says, 'Hey, if you aren't already rich you can't play here.' but that's not fair, is it? We are on your side, we're here to make you rich not to make rich people richer. Sure you can invest your 401k in so called 'index' funds, but with our clients will put it in a dozen different startups, anyone one could make you a millionaire and if two or more make it big, well lets just say I hope you remember the guy that made it possible for you. So are you in or not?"
Wefunder, FundersClub, the initial round of crowdfunding will all (hopefully) be great success stories. And if they are successful someone is going to create the "Countrywide" equivalent to them and fleece a ton of people. That is my fear and I don't know how to prevent it.
