Human resources are wasted under the capitalist system because of its basic motivation for profit rather than social welfare. The major profits of production return to the non-productive section of society - the artificially created property-owner class, the bourgeoisie. The proletariat, unable to acquire property, are denied self-development and therefore remain dependent wage-earners. With developments in science and technology, machines begin to take over the role of human labour, which is found to be too expensive in the quest for ever higher profits.
