“Democracy sustains capitalism. Capitalism thrives in a democracy. And, right now, we are dealing with, as I called him at my speech on the Ellipse, a tyrant,” she said, referencing her rally last year on the White House Ellipse in Washington. “We used to compare the strength of our democracy to communist dictators. That’s what we’re dealing with right now in Donald Trump. And these titans of industry are not speaking up,”
Short answer is no.
Long Answer: Communism is an economic progression from capitalism where things aren’t produced for profit/money, but for it’s use value to fulfill needs, where private property and capitalists as a class are abolished.
(Partial) State ownership is something that would happen in a period of transition after workers have took over the state and toppled the capitalists (in US case it’d be all the political parties, government and organs serving it), with all of their private property being repurposed to building up the production - it’s what’s called state capitalism or transitory period, not communism or socialism, as things are still being distributed for money, which means markets, etc.
However, capitalist liberal democratic countries can just own stuff. Mussolini’s Italy for instance had owned a large share of factories, countries such as US/UK had nationalized industry during ww2, there’s tons of EU countries right now that have partial ownership in private companies or have complete national ownership of certain companies (mostly transport or broadcasting).
In other words, it’s heavily contextual, not unique to the building of communism, and Trump’s acquisitions if you look a closer look at them are less of “we control you now” and more like US becoming a shareholder like a private individual (they don’t even have the seat at the board apparently) so none of the explanation was relevant and it’s just a weird way of managing some crisis (probably).
