Here in the United States, which exists as a yin-yang balance between capitalism (for-profit, privately owned) and socialism (taxpayer-funded, people-owned) by our Founding Fathers' deliberate design, the concept of "people owned" is an integral part of being a representative democratic republic. Too much capitalism without the balance of people-governed oversight (socialism) and regulations (socialism) unleashes bottomless-pit corporate greed and corruption. Conversely, too much people-owned socialism without the impetus and competition of capitalism can lead to slow economic growth or stagnation. We need the balance of both.
Examples of socialism in the U.S. include, but are not limited to the following: the military; our courts at city, state, and federal levels; police and firefighters; highways, roadways; bridges and tunnels; mass and public transportation; city, state, and national parks; Social Security; Medicare and Medicaid; oversight and regulatory agencies such as the FAA, FDA, EPA, FTC, OSHA (workplace safety), our nation's public schools and colleges; and so on.
The book "DARK MONEY: The Hidden History of the Billionaires Behind the Rise of the Radical Right" (2017) by Jane Mayer exposes domestic-terrorism and anti-democracy villainy of the Koch brothers, Charles and David, and their very secretive KOCH DONOR NETWORK of would-be plutocratic billionaires seeking absolute power (to be corrupt, absolutely)---a pattern copied by the anti-democracy ruthless KGB-trained Vladimir Putin and his Russian MAFIA delegates: "The Plot to Destroy Democracy: How Putin and His Spies Are Undermining America and Dismantling the West" (2018) by career CIA counterespionage expert Malcolm Nance. Our yin-yang balance needed to remain strong has been under attack as indicated in these two revealing books.
