Enact a policy which would require international corporations to abide by the constitution abroad, and in Cyberspace

The Bill of Rights is law in the United States, it recognizes the freedoms and liberties bestowed upon us by our creator, and makes them inalienable. These laws are not present in developing nations, such as China, or Vietnam, and as such, multinational corporations are free to exploit this lack of rights to make a profit. This does not only hurt the citizens in these developing nations, it also damages the economy of the United States.
In exploiting slave labor, these corporations do not have incentive to hire workers in the United States, hurting the working class and in doing so, hurting the economy.
This alone is mostly a foreign policy, but when dealing with the United States with slave-made goods, additional tariffs should be enacted on these corporations.
