The problem with Amway was never anything with their products. It was the corruption of the MLM concept into the notion that it was a get rich scheme. Some of the more successful dealers promoted the concept that you could just amass a large number of underlings and sit back and get rich. There was never the idea that you sell a product. You sold a pathway to wealth. They sold a religion. No one wanted to slug it out just selling soap, making a modest (or substantial) gain from it part time (or full time), and sharing it with others who wanted to do the same.
That corrupt model has been used successfully over a full spectrum of "sales pitches" to make people feel that they want to belong to such an organization.
If you're a Snap~On independent dealer, the sales manager is telling you to get every last $5 bill out of the mechanic's wallet.
"Not only do you need that $5 bill, you deserve it." ..since the independent dealer is, in fact, a customer of Snap~On and making your primary customer feel good in reaching very high and deep is what produces the most profits.
They all attempt to distinguish some form of "us" and "them" in some exclusive separatist group with all kinds of ego stroking and whatnot.
We've seen this many times ..and not just from soap salesmen.
