I'd like to see you walk into any economics class in this world and make this argument about Karl Marx being in favor of unrestricted free-market capitalism (free trade). Can you show me what examples you have that you would use to make this argument?
Is that like, unrestricted in the since Lenin and Stalin and Mao and Hitler were unrestricted. Should we not restrict ourselves in feeding those types of maws?
This is the entire point of the post...the free market that became the envy of the world, did so precisely because it was based on a fundamental moral foundation. The people were unrestricted because they restricted themselves through their moral conscience.
If you remove that little tid bit from the equation, you do not have the free market anymore.
When you invite the immoral, totalitarian to play on your field, you undercut and corrupt the very most basic nature of the free market and corrupt it.
Our policy in foreign trade, and the constitution provided for it, should be to avoid that happening and trade with those, and open our market up to those, who play on the same playing field we have created...and restrict those who do not until they show signs of doing so. Otherwise, you may have unrestricted free trade...but you do not have the free market that produced the wealth we currently enjoy.
Just my opinion.
Get a copy of his speech to the Democratic Association of Brussels at its public meeting of January 9, 1848. In it he concludes, "...the protective system of our day is conservative, while the free trade system is destructive. It breaks up old nationalities and pushes the antagonism of the proletariat and the bourgeoisie to the extreme point. In a word, the free trade system hastens the social revolution. It is in this revolutionary sense alone, gentlemen, that I vote in favor of free trade.
