People pay top dollar for bugs, as long as they're from the ocean (shrimp, lobster, crab). It's all just a matter of marketing.
I met someone from Newfoundland. When she was small, she and the other kids ate lobster day in and day out. Well, except for the rich kids; the rich kids ate peanut butter.
Yes, lobster used to be considered crap food; then it became fashionable and the poor couldn't afford it anymore.
Depends where you live, cities are still growing, like in Japan Tokyo still grows while the rest of the country shrinks.
