Fifty years ago, ingredients in food were actual food -- milk, sugar, eggs, wheat, etc.
Now ingredients are artificial colors, artificial flavors, GMOs, and all types of chemicals that should never be in food (titanium dioxide, propylene glycol, glyphosate, hydrogenated oil, sucralose, etc etc etc).
If they could produce food with all real ingredients back then, they could easily do it now.
They just choose not to.

Eliminating all Frankenfood is the only acceptable course of action.
