As metropolitan regions grow ever larger it is hard for their governing bodies to be responsive to the needs of all of the people. Nation-states with a megapolitan capital city tend to override neighbourhoods and neighbourhood culture. This pattern is repeated in other metropolises. Thus the different languages, customs and cultures that exist at present may disappear in their areas over time. Efficiency is the only value that emerges in these vast conglomerations; and mechanization and routine demand the subordination of the individual to the masters of the city-state.
