Communism is a political ideology that calls for public ownership of major resources as well as the means of production, so that the state, rather than private individuals or corporations, owns factories, farms, mines, and so on. Communism has never been popular in the United States, and the only politician calling for state takeover of private industries is Trump, under whom the government has taken stakes in at least nine companies involved in steel, minerals, nuclear energy, and semiconductors, costing at least $10 billion in taxpayer money.
