Which strongly suggests that the real problem is ideological polemics, which makes sense when you think about it. The USA didn't stick to ideological capitalism, and implemented many "socialist" policies: welfare systems, public works projects, labour protections, public infrastructure, etc. etc. The USSR did stick to ideological communism as they defined it. Markets weren't utilized at all. Freedom of thought was suppressed. Political purges were executed. In the USA, something similar was tried with the "red scare", but thankfully plurality won out, and some of those "abhorrent" socialist policies became mainstays in "great capitalist America" as part of the New Deal, which is what saved the USA from its domestic communist movement. Over the last few decades though, the USA seems to have forgotten this. Forgotten that what saved the USA was not rigid adherence to some pre-existing quasi-religious ideological/spiritual polemic (which both capitalism and communism are), but the willingness to implement and incorporate a wide basket of ideas as they were appropriate.
