Corporations are machines. You would be foolish to make a compact with a machine. Actually, you might have more success making a compact with your toaster.
As machines, they only have two obligations, both closely tied to their survival:
A)Produce money for the owners/shareholders
B)Obey the laws of the countries in which they do busines
These international corporations are basically powerful enough that B no longer really applies. They can have laws re-written for their benefit. The laws of our nation are basically gotten around and their original intent offset by the fact that they can move certain operations to places where those laws do not apply, but still profit by doing business here.
These multi-national corporations are no longer just machines, nor do they any longer truly obey the laws of supply and demand. They are harmful to our nation, and belligerent to our form of governance.
