The strongest factor in a culture is attitude. Food is peripheral. And as the left saw in November (despite Hillary’s typical democrat strategy of faking a pro-American attitude during the campaign), many decades of anti-American attitude by the elites was answered by the monolith known as American culture.
No. The food that is available, and how available it is creates the attitude. Areas of food hardship build cultures that put much more stock in the meaning of sharing, areas of plenty build cultures that put much more stock on variety of experience.
Remember, if Hillary isn’t the most unlikable person to ever run for president, and she actually bothers to fight for the Rustbelt, she’s president right now. “The monolith” gave her the win, luckily the Founding Fathers were much smarter than you, understood that America was a collection of micro-cultures, and structured an electoral method that demanded the candidates win as many micro-cultures as possible and Hillary failed.
