This interest can best be satisfied by allowing the carrier freedom in the making of its schedules--subject only to review in particular cases.

Special instances may always exist of unnecessarily high or excessively discriminatory rates; and provisions should be made for the consideration of such cases, perhaps, by some court specially organized for the purpose; but the assumption should be, on the whole, that the matter of rates and service can be left to the interest of the corporation itself.

In no other way can the American economic system retain that flexibility with which its past efficiency has been associated.

In no other way can the policy of these corporations continue to be, as it has so often been in the past, in an economic sense genuinely constructive.

This flexibility frequently requires readjustments in the conditions of local industry which cause grave losses to individuals or even communities; but it is just such readjustments which are necessary to continued economic efficiency; and it is just such readjustments which would tend to be prevented by an official rate-making authority.
