When I worked at the newspaper, they would offer promos and discount rates for all kinds of stuff. New subscribers. Pay by mail. Pay by the month. 6 month. 1 year. Senior discounts. All kinds of stuff. It got to the point that they had several dozen different rates. So you're getting the paper at X price as a new subscriber, but your elderly neighbor, whose been a faithful customer for decades is paying many times X for theirs. They find out and complain. So you give them a discount. Then they call all of their elderly friends and tell them to call and complain. Then they do. Then everyone starts. Eventually, they won't take the excuse that their neighbors are getting it for a one-time promotional price, and will eventually be paying the same price you are. That still doesn't sit with them, and they cancel.
They hired a company that came in and analyzed the rate charts, and ran it through an algorithm that accurately predicted that if they raised their rates on all of their customers, some would cancel, some would stay, but the ones that stayed paying the higher rates would offset the ones that cancelled at the lower rates. So you now have less product to produce and deliver to less people, which requires less raw materials, less electricity, less fuel and fewer delivery vehicles, smaller warehoused and fewer employees, all while still making the same amount of money. So go ahead and quit our product, we don't need you. That's pretty much what happened in almost the entire newspaper industry.
It's also what's happening in many other industries. They have it figured out that even if they raise their prices so much that people stop buying their product (whatever it is), enough people will keep buying it at the higher prices to offset any lost customers and sales.
Look around and see if you can find any industries that cannot sell their products right now.
