One of the major issues with MLM schemes, and I'm sure this is another factor with the FTC's proposed rules, is the Ponzi or pyramid problem: eventually you run out of people to recruit. Once you get friends, nearby relatives, and neighbors set up as reps under you, whom will they sell to? Other reps? That's too many reps for the product in a small area.
The feds investigated the dreaded Amway for several years in the 1970s before ruling that the company was legal only because there were bona fide products involved. That's not to say that anyone at the low end has really made any money from selling the stuff; many have lost significant $$$. Like it or not, many people lump Amsoil in with these other MLM outfits. And I've already commented on how many Amsoil reps were far more interested in setting me up under them than in actually selling the product.
Long-term, Amsoil would be better served by setting up territorial sales reps to prevent the problem of too many reps in an area poaching one another's sales. Your Amsoil territory could be a town, part of a city, a county, an area of so many square miles, etc. This is, very roughly and with exceptions, the approach that some of the cosmetics companies such as Avon have taken, as well as has Texas Refinery Corp. with its lube and protective coatings lines. Your wife/girlfriend calls Avon for a contact to get a catalogue and buy Avon products, and she will get the name of the one rep for her area/address (not the two dozen reps as might be the case with MLM companies).
The lifetime and more successful existing Amsoil reps could be given first crack at becoming territorial reps. There would be no more recruiting others to sell and splitting proceeds. The rep would sell the product, not the franchise. And isn't that why Amsoil exists in the first place: to move the product?
When Al passes the reins, it wouldn't be too surprising if his successor makes a change like this. That would be doubly true if the FTC makes it too onerous for an honest company like Amsoil to maintain the MLM system.
