Marx saw capitalism as a system for the production of goods. All productions in capitalism aim the market. For production, hired labour is used. In Marx’s view, all economic systems are also social systems. Each style of manufacture (slavery, feudalism, capitalism) gives birth to a certain class structure. Marx pointed out that in the economic system, the only important thing is not just the goods. Relations between people are an important aspect also. People are connected through the manufacturing (Production) process.
In the capitalist production system, labour itself becomes a kind of goods. The workers are forced to sell their work power in the market. This creates two important classes – capitalists and workers.
