Marx was right in that free trade was destructive and would lead to socialism then communism.
You are so wrong, free trade has no relationship to the spread of communism.
What we have today is not free trade, we have remnants of our convoluted trade policies from right after WW II.
Uncle sugar gave away US tax payer dollars many via trade policies, trying to rebuild the world and buy friends around the globe.
Today's free trade is comparable to our payment to the UN, we pay the lions share, and get pissed on by the entire world
