It's more or less a universal model that won't change. Many businesses are based on cheap labor, not market demand for the products. Dinner salads were unknown until someone figured out that lettuce can be grown cheaply by immigrant workers. Advertising and promotion did the rest.
I disagree. I don't need cheap shit produced or served by underpaid serfs. I don't WANT IT.
I want a society of equals, not serfs, peasants and nobles.
