the governing rights of the States are all of those which have not been surrendered to the National Government by the Constitution or its amendments.

“As a matter of fact and law, the governing rights of the States are all of those which have not been
surrendered to the National Government by the Constitution or its amendments. Wisely or unwisely,
people know that under the Eighteenth Amendment Congress has been given the right to legislate on this particular subject, but this is not the case in the matter of a great number of other vital problems of government, such as the conduct of public utilities, of banks, of insurance, of business, of agriculture, of education, of social welfare and of a dozen other important features. In these, Washington must not be encouraged to interfere.”
