What our Federal government should be

The true theory of our Constitution is surely the wisest and best, that the States are independent as to everything within themselves, and united as to everything respecting foreign affairs. Let the General Government be reduced to foreign concerns only, and let our affairs be disentangled from those of all other nations, except as to commerce, which the merchants will manage the better, the more they are left free to manage for themselves, and our General Government may be reduced to a very simple organization, and a very inexpensive one; a few plain duties to be performed by a few servants.

Tenth Amendment

I consider the foundation of the Constitution as laid on this ground: That ‘all powers not delegated to the United States, by the Constitution, nor prohibited by it to the States, are reserved to the States or to the people’ (10th Amendment). To take a single step beyond the boundaries thus specifically drawn around the powers of Congress, is to take possession of a boundless field of power, no longer susceptible to any definition.
