It hasn't been debunked. The right only claims it has been debunked, and then claims I am trolling for not resorting to fallacy.
Immigration into the Union is not a State concern since 1808,
We have laws regarding employment at will.
I think we need a Policy of Truth.
It is why no one takes the right seriously about economics or the law.
Again.....that conclusion is "oxymoronic". If state borders were not important there would be no state borders.
Perhaps you have never heard of the Immigration and Nationality Act? The constitution grants authority to Congress the power to "....establish a uniform rule of naturalization". -- Article 1 Section 8 Clause 4. Congress used this authority to establish the Immigration and Nationality Act along with various and sundry other provisions related to immigration.
The provisions encourage both formal and informal partnerships between federal, state and local law enforcement agencies. States are expressly granted the authority to address illegal immigration through their traditional police power reserved under Amendment #10....thus Congress has acted to ensure that states can and will cooperate with the federal government to help enforce immigration laws.
The only exception to this Act of Congress rests with any conflict that comes between state law and federal immigration law....the federal law preempts state law in such circumstance....only.
And the Courts have ruled as much. Az. v United States. Clearly the courts declared that Az. was within its rights to request Identification of citizenship or immigration papers when requested by state or local law enforcement agencies.
Further the Supreme Court settled the dispute made by some which held the opinion that the States have no rights of enforcing federal law. They ruled that federal law "DOES NOT EXCLUDE THE STATE OF ARIZONA" from enforcing employee verification federal law.

Of course this was already known from countless established precedents going back to the last century.
To argue that no state has the inherit right or responsibility to enforce federal law promotes anarchy....not the rule of law.
