Property is held and transferred on terms fixed by the States. In short, the structure of social and business relationship is built chiefly about the laws of the States. It depends upon the exercise by the States of that vastly greater share of Government power which resides in them, to the exclusion cf the Federal Government. In ordinary times nearly the entire burden of taxation represents State and local demands. Even now, despite the enormous increase of Federal taxes from pre-war years, State and local taxes far exceed the Federal requirements. Moreover, the national burden is being continually reduced, while that of the local units is growing and likely to continue to grow.
