There's plenty affordable fast food out there, just not at McDonalds. McDonalds and other publicly traded fast food companies have jacked up prices to pay their shareholders while simultaneously decreasing quality and service across the board. Meanwhile, I've got a regional burger chain near me where I can get a double cheeseburger with fries for $5 that's way more substantial than anything McDonalds offers.
This isn't "a boring dystopia," this is just people dumping McDonalds, which is a good thing.
