Lefties demand that multi-level companies be investigated by the "authorities" and destroyed. The only problem is that if you try to keep people from taking their own risks and spending their own money, you have to take away their liberty to start a business of any kind.
There's an abundance of information available on these companies, both the good and the bad. Caveat emptor is just not that tough. Nu Skin is a long-lived, solid company that's quite ethical. Not that I can imagine myself being in essentially 24-hour retail sales. But there's nothing intrinsically wrong with the business model for those who can.
What Lefties don't like about multi-level companies is that about 85 percent of the distributors are family-oriented, self-starting, free-market conservatives.
It’s the million dollar shell companies that’s the problem up there. (And the fines don’t speak too well, either.)
