Understanding the true distinction stems from Karl Marx’s writings. Marx viewed socialism not as an ideal end but as a "necessary scaffolding" towards communism. In his Critique of the Gotha Program, Marx articulated that socialism is the stage where "from each according to his ability, to each according to his contribution" is practiced. This phase prepares society for the ultimate goal—communism, where "to each according to his needs" becomes the rule, and class distinctions dissolve.
