Karl Marx was dead against capitalism. He argued that industrial society was based on capitalism. Capitalists owned the capital invested in factories and the profit of capitalists was produced by workers. The conditions of workers could not improve as long as this profit was accumulated by private capitalists. Hence, it is essential to overthrow private capitalists. This would finally destroy the rule of private property. Marx wanted the workers to construct a radically socialist society where all property was socially controlled. This was the only way through which they would free themselves from capitalist exploitation.
