Some of it is ego. Dr Dalton is the sorta man that for example wants to build a huge city. He finds the land, builds all the house and buildings. Turns on the lights and water in the city. Sells house and rents out the businesses. Finds people to move to the city. Then he tells people that he built a city and here it is.
