Annie Lowery, a business reporter, wrote the book Give People Money: How a Universal Basic Income Would End Poverty, Revolutionize Work, and Remake the World, which advocates that the federal government adopt a universal basic income(UBI) under which every person in the country would receive a monthly check of $500 to $1,000.

A Gallup public opinion poll indicates that among people aged 18 to 29, more have a favorable view of socialism than of capitalism. A columnist in the Wall Street Journal comments: "Would these people actually know socialism if they saw it? Taxing the rich, Medicare-for-all, and a Green New Deal that replaces fossil fuels with renewables are certainly liberal, probably radical, possibly unwise. But socialist? Hardly." What definition of socialism is the columnist using if he doesn't consider the programs he lists to be socialist? Is the columnist's definition of socialism one that U.S. socialists like Senator Bernie Sanders and Congresswoman Alexandria Ocasio-Cortez would be likely to accept? The columnist is likely defining socialism to refer to a
centrally planned economy in which the government directly controls most production. Bernie Sanders would be unlikely to accept this definition of socialism because he is more concerned with the provision of services such as health care and not government ownership of businesses.
