The end goal of socialism is always communism.
In 1988 democratic-socialist Bernie Sanders traveled to the Soviet Union for a honeymoon with his wife, he had a really awesome time! Like, super awesome!
After Bernie got back to America he couldn't stop raving about how impressed he was with the Soviet Union.
Here he is in 1988 after returning from his trip, singing the praises of the Soviets in a public setting. He's not even trying to hide it.
