Interesting, but I wouldn't oversimplify this to one cause. Home cooking of meals and making of lemonade/fruit punch used to be a norm. Society chose to move towards taking a lazy way out with microwave dinners and takeouts. On the other hand, Asian countries have healthier fresh made bento boxes in convenience stores so it's not time saving alone. At the end of the day, companies deliver what consumers want and try to discern demand, what else are they supposed to do?
