Socialism is communism lite. Period. True socialism requires that the central authority (government) controls the money. And socialists somehow don’t believe that absolute control of all a country’s money won’t corrupt the government leaders the way they claim all rich capitalists are corrupted by it?
Basically, you start with a little socialism. Something that sounds reasonable, like Social Security. But people get a taste of being taken care of by the government, so they elect people who promise them a little bit bigger slice of socialist pie. Which requires taking more money from the people who make it. Therefore more people need the government to help them, requiring more money from everyone else. This goes on until the government simply controls everything and gives everyone an equal amount of the little bit of money that’s left.
