How did economic opportunity divide urban and rural dwellers?

Economic opportunity divides urban and rural dwellers. Traditionally and historically, there are greater economic opportunities in urban areas. In urban areas, more people are concentrated in a smaller space, resulting in a need for a greater number of shops where these people can buy the goods they require. There is also a greater need for adequate transport systems. Wide enough roads need to be built to accommodate a greater number of cars and busses. This creates jobs for people as the roads need to be built and maintained.
