Since we already live in a world with dystopian elements, why not one more?
Just imagine, 50 years from now, all people will consume soylent, or something like it. Just enough nutrition to keep us alive and relatively well, but not enough protein to keep us strong or intelligent. Hunger will be a luxury and those with the means to sate their hunger will be of the luxury class. They will laugh at the complaints of yesteryear, complaints about $8 organic eggplants, because in their time, eggplants will cost $8,000 dollars each . . .
