The reason distribution companies like Amway and Tupperware exist in the first place dates from a very different time and very different America. In the mid 20th century, you had American families by the thousands moving far away from the usual large population centers such as NYC, where you could get what you needed down at the corner store, and you had busy middle-class housewives who rarely had time for leisurely shopping, especially when they had kids to take care of, so, taking a page from the peddlers of the 19th century, companies sprung up that took their products to the customer rather than waiting for the customers to come to them. Amway distributors, Avon ladies, Tupperware parties, Mary Kay saleswomen, Fuller Brush salesmen, etc., these were all a familiar part of postwar America. But why would modern Americans, who can tap a button or two on their smartphone and have their favorite laundry detergent arrive at their doorstep in a couple of hours or a couple of days, embrace an old-fashioned business model that made more sense to their mothers and grandmothers? That's why they're considered scams now, because, in their view, only those aiming to get rich quick would want to participate.
