But these legitimate economic responsibilities are not very numerous or very onerous compared to those which should be left to the central government on the one hand or to the municipal governments on the other.

A municipality is a living center of economic activity--a genuine case of essentially local economic interests.

To be sure, the greater part of the manufacturing or commercial business transacted in a city belongs undubitably to the national economic system; but there is a minor part which is exclusively local.

Public service corporations which control franchises in cities do not enter into inter-state commerce at all--except in those unusual cases (as in New York) where certain parts of the economic municipal body are situated in another state.

They should be subject, consequently, to municipal jurisdiction and only that.
