To treat a nation as an enemy simply because its people offer us quality goods a low prices is hardly a mark of civilization. Protectionism is a violation of the government's legitimate jurisdiction. A free society requires a limited government which is restricted to enforcing justice and barred from attempting to manipulate the economy. By confiscating money from foreigners and interfering with our economic decisions, the federal government becomes tyrannical. While the government must raise revenue, it ought to do so in an equitable an restrained fashion.
Protectionism places an unjust burden on the citizenry.
Enforcing import restrictions and stamping out smuggling requires a bloated federal government which must be supported by taxpayers. We all know this is the case with the jihad for drug prohibition, and it applied to other foreign imports as well. In additional to this tax burden, tariffs also lower our standard of living by encouraging inefficiency in domestic industries. It makes no economic sense. And besides, it's socialism.
