What type of economic systems did Karl Marx propose as a solution to class struggles?

Karl Marx proposed socialism as a solution to class struggles, emphasizing the need for a system where the means of production are owned and controlled collectively rather than privately. He believed that capitalism inherently leads to class conflict, as it creates a division between the bourgeoisie (capitalist class) and the proletariat (working class). In Marx's view, socialism would abolish private ownership of the means of production, ensuring that goods and services are produced for the benefit of society as a whole rather than for profit. This transition was seen as a necessary step towards achieving a classless society where resources are distributed more equitably.

The other options represent different economic systems: capitalism is characterized by private ownership and market-driven economies, laissez-faire promotes minimal government intervention in the economy, and feudalism is a historical system based on land ownership and a rigid class structure. These systems, in contrast to socialism, do not address the class inequalities and struggles that Marx critiqued.
