American politicians are, for very good reasons, defensive about coming off as Socialist (except Bernie Sanders). Coming off as Marxist is completely out of the picture.
But 'patio11 is not a politician and I expect his language reflects strength of feeling more than anything else.
Healthy marxism and healthy capitalism actually look pretty similar. A free market for people, aware of their market value and able to move between employers without artificial restriction looks a whole lot like the proletariat seizing the means of production.

Yes, you said that in the opening sentence... Americans are very defensive about coming off as "Marxist"/"socialist".
