Most authorities in economics and sociology regard such an organization as a city an impossible structure, not only from the economic standpoint, but from the sociological and psychological as well. No creature of the highly nervous structure necessary to develop a culture, they point out, would be able to survive within such restricted limits. The result, if it were tried, these authorities say, would lead to mass neuroticism which in a short period of time would destroy the very culture which had built the city.
