In the US during the time period of The Grapes of Wrath, socialism had one definition, communism, and the US was strictly against it. During the first red scare (1917), the US was still rapidly expanding due to immigration from European and Asian countries. As a result, the first to be blamed for the possible communist influence in America were Eastern European immigrants, whom were believed to have been involved in the Bolshevik Revolution. Unfortunately, the scare that was a direct result of all this would cause immigrants to be treated unfairly and falsely accused. In "Grapes of Wrath", the treatment of the "Okies" is similar to the treatment of those who were seen as communist in America during the red scare. Americans, who were supposed to treat everyone equally, were once again throwing each other under the bus because of an affiliation. For example, Tom is a convict, yet the truck driver only saw a convict and not Tom for who he actually is.
Socialism is an economic system where everyone equally owns production. Allocation is according to contribution. Here are pros, cons and examples.
