If I hadn’t just got off a 8 hour flight I’d explain why you are extremely wrong in greater detail. But taking one example, agrial, who own many branded prepackaged foods have 2 or 3 processing plants on the entire African continent, in comparison they have 3+ in Spain alone. These companies don’t go into countries to make it a better place, it’s cheap labour and crappy work conditions.
The environmental and nutritional issues around pre packaged foods are massive. And with the environmental, it’s the poorest who will be impacted the most. You think the world is at each other’s throats now? Just wait until you add food shortages (heck look at Venezuela for an example of how lack of food can escalate things) and extreme weather patterns. If you want to help ‘villagers in Africa have jobs’, support sustainable industries and charities. Don’t pat yourself on the back for being lazy, because truthfully that’s what it is. Western laziness.
