success of capitalist economy to provide affordable food to millions.
Food for poor was never the best, for one, because of price of quality, and two, the reason for poverty is often a simple mind and bad character.
So, no need to deflect the point here, which is this had never happened in history. Poor people are fat as ancient Chinese emperors (probably not healthy food there too).
And it make the point that even if you provide the poor with abundant food, they will still not be happy, not become rich, and won't even pick the good food instead of trash food.
What is the difference between a fast food meal and a bag of raw food that when prepared constitutes a healthy, and several larger meals?
