The samples are picked to illustrate the point, rather than the point being derived from random samples. The Ohio State Government is in a 40-story skyscraper in the center of Columbus and also occupies a major portion of another skyscraper. Why is that not in this post.
Chinese local governments handle more stuff than the village halls here. Notably, economic affairs. The government owns and finances a major portion of the local industries, and I do see a need for them to model the government buildings after the business buildings.
