@Sarthak_7204 Yeah the a man with excavator produce more value but once the production method becomes generalised, the social necessary labour time required to produce that commodity falls, which reduce the value of that commodity. So no more value afterwards.
Socialists don't believe that wealth is pre-existing rather they recognise that wealth is created by labour power which is constantly exploited by the rich for endless valorisation. They also understand redistribution is a stabilizing mechanism that prevents economic instability.
There is all the difference in the world between takers and makers.
Production never even crosses their minds. Like parasites, socialists exist solely to take and consume, never to create or contribute.
Capitalism is in fact based on the exploitation of the surplus value which is created by the working class people. It might seem like it's just trade but deep down it's diplomatic theft.
“Capitalism was the only system in history where wealth was not acquired by looting, but by production, not by force, but by trade, the only system that stood for man’s right to his own mind, to his work, to his life, to his happiness, to himself.”
