Or alternatively "If you aren't already rich, you don't get marketed at by people offering opportunities so bad they've been passed on by high-risk investors who underperform the returns the non-rich get on less risky asset classes despite working full time on managing their investments whilst having significant power to induce exits in their favour." Or rather, the general public actually does have the opportunity to invest in startups if introduced by genuine friends and family but random mountebanks don't have the right to run slick campaigns to dupe non-rich people into believing that Startup X is a good place to put life savings despite offering lower expected returns than a roulette wheel and zero liquidity. I mean, it'd be nice if the law was as restrictive on more blatant attempts to scam like penny stock pump and dumps and MLM, but it's difficult to argue the general public would be better off for having comparatively sincere people beguile them with Powerpoints involving hockey stick curves.
It's not a "Rich Get Richer" provision when it's obvious that on average the poor will get poorer from random startups being able to present themselves as investment opportunities to them.
