How so? Was Marx right or wrong about free trade eliminating capitalism? When did Marx write those words? Since then, how many more countries have adopted capitalist bases economic systems vs. what they had before?
That's not germane to my point.
Marx advocated for free trade to destroy the middle class and nations' sovereignty. It was a means to an end for him to achieve his objectives.
So, it doesn't matter that he was "wrong." (Actually, more countries are adopting socialist, statist policies than capitalism). What matters is this revolution.
