I bet you didn't know that ther was an E.P.C.O.T built in the latter half of the 19th century. It was built on the south side of Chicago, and it was called Pullman
The Town of Pullman
The model industrial town of Pullman, Illinois had its beginning on May 26, 1880, in the open prarie. This town was the physical expression of an idea born and nurtured in the mind of George M. Pullman, President of the Pullman Palace Car Company.
He decided to develop a model community, a total environment, superior to that available to the working class elsewhere. By so doing, he hoped to avoid strikes, attract the most skilled workers and attain greater productivity as a result of the better health and spirit of his employees.
Pullman realized the necessity of building his town it would have accessibility to the big city markets and railroad connections with the enitre country. The 4,000 acre tract selected for the site lay along the western shore of Lake Calumet directly south of Chicago, approximately 13 miles. It was essentially open prarie land linked to Chicago by the Illinois Central Railroad.
George Pullman hired Solon S. Beaman, landscape architect Nathan F. Barrett and civil engineer, Benzette Williams, to translate his plans into three-dimensional reality.
Construction of the town was executed by Pullman employees. Structures were made of brick fashioned from clay found on the company site. Pullman shops produced component parts used throughout the building of the town. This project was one of the first applications of industrial technology and mass production in the construction of a large-scale housing development.
Each dwelling was provided with gas and water, access to complete sanitary facilities and abundant quantities of sunlight and fresh air.
These factors brought Pullman to be voted the world's most perfect town at the Prague International Hygenic and Pharmaceutical Exposition of 1896.
Sounds a bit like what walt wanted but in aa 21st Century era
