ELI5: If scam companies live Vector and Amway have been screwing people (mainly students) for so long, how come no legal action has been made to take them down?

Because theoretically it is a legitimate business. While it may seem like craziness, there are truly some very successful people who have been able to either sell the product they are forced to buy, or have signed up enough people to gain that residual income. 

While the business screws people over(who have to buy product in order to attempt success), there is nothing illegal about it. And it is completely elective. Funds aren't being fraudulently redistributed to make it appear like there is a profit, a la a Ponzi scheme. It is a  shady way to do business that victimizes illusions of grandeur, yes... just not illegal.
