“ They grow out of our complex system of government, and out of the fact that the authority of the National government is legitimately exercised within the States. While it is true that government cannot exercise its power of taxation so as to destroy the State governments, or embarrass their lawful action, it is equally true that the States may not levy taxes the direct effect of which shall be to hinder the exercise of any powers which belong to the National government. The Constitution contemplates that none of those powers may be restrained by State legislation. ”
