I would argue that a hamburger costing only $1 is very loosely using the ingredients you think it is.
If we don't see a decade of economic downturn, in 1-2 decades McDonald's may turn into something decently healthy/acceptable, once again in the sense of still being fast food.
We could however see the dystopia of McDonald's only accepting fixed amount of meme doge tokens that go on to hyperinflate, and we'll all be able to shake our fists about how we were promised flying cars but got DogeDonalds
This guy thinks the Big Mac should cost $200
