Also, what you describe has been done before in history. In the 19th century in the US there were "Pullman Towns" - everything from A to Z owned by the Pullman company.
"Get baptized in a Pullman church, go to a Pullman school, work for Pullman all your life, and get buried in a Pullman graveyard." was an activist slogan at the time. (I learned this from history class at university, paraphrasing from memory).
