I tend to disagree and let me say why.
The statement of the fringe extremes of both ends of the spectrum do seem to avoid the outright support of government takeovers of industry and production, but their tinkering around the edges of these ideas makes me think the idea is only repressed for appearances.
Look at the lefts demonetization of corporations and tell me that they do not hate these enterprises and would be quite content to have them totally controlled by government, lock stock and barrel. Minimum wages are also a nationalistic ideal.
Look at statements from the likes of Pat Buchanan and others that want to control the activities of businesses through regulation of their ability to trade without regard to the company's survival. The outsourcing issue is bringing desires of goverment control of business.
The New York Stock Exchange debacle drew many to proclaim that a person made too much money! Now they have regulated compensation.
I don't know, but it seems to me that many would be quite happy to have the nations corporations under the control of government where they think they would have some say in the day to day activities of same.
While they collectively never use the word National in their diatribes, the general gist of what they want to do is the same.
