Here's some "Soros funded propaganda" for you:
1. The meaning of the Phrase "to regulate trade" must be sought in the general use of it, in other words in the objects to which the power was generally understood to be applicable, when the Phrase was inserted in the Constn.
2. The power has been understood and used by all commercial & manufacturing Nations as embracing the object of encouraging manufactures. It is believed that not a single exception can be named.
