Not a very consistent statement, to say the least.
Cutting domestic corporate taxes I agree with, however.
Sure it is. Although it doesn't specify an economic system per se, our Founders essentially designed a wonderous free market when they drew up the Constitution. Free Trade among the several states who were signatories to the Constitution, bound by a common set of rules, regulations and currency. The Founders considered the tariff to be the least intrusive form of taxation, applicable only to those wishing dependence on foreign goods. Domesticly, Americans were free to enjoy the blessings of their own resources and hard labor, subject to neither income nor sales tax.
It is unconscionable to extend the blessings of our domestic free market to foreign entities not bound by the same set of rules and regulations established by our Constitution to the detriment of our own citizenry.
