Instead, the government or the whole community owns these things. Everyone is supposed to share the wealth that they create.
After World War II, Americans became fearful of the spread of Soviet communism. This fear was fed by the news media and politicians who portrayed the Soviets as bent on world domination.
In communist nations, people were not allowed to own land, follow their religious beliefs, or speak and act freely. Americans were afraid that the Soviets would take over the U.S. and take away their freedoms.
