I used this analogy:
Imagine you're at a food court that has waiters. You order from any vendor, and the waiters bring it to you. You pay the vendors separately for your food, and you pay the waiters for the trays. Some people order five trays, some people just a couple. But the waiters get paid by the tray, not for what's on it.
Imagine the waiters got together, and said "Hey, let's start charging more for people who want beluga, they can afford it." Once that was accepted, you can be sure that fairly soon boeuf bourgignogne, Bordeau, and blueberries would be extra cost as well, eventually only leaving baloney and Beef-a-roni as the "basic options".
Is this good for the vendors? No. As the price goes up for their options, their sales suffer. Is it good for the diners? No, they have to pay more to get the exact same stuff. Is it good for the waiters? Undoubtedly!
