Is capitalism absolutely the only viable economic system so yes this is true and right ?

No, capitalism is not the only viable economic system. There are other economic systems such as socialism, communism, and mixed economies that have been implemented successfully in various countries around the world. Each system has its own strengths and weaknesses, and the best economic system for a particular country depends on its unique circumstances and goals.

No, capitalism is not absolutely the only viable economic system.

Here are some of the other economic systems that have been implemented in different countries throughout history:

- Socialism: A system in which the government owns and controls the means of production.
- Communism: A system in which there is no private property or social classes, and the government controls all aspects of the economy.
- Feudalism: A system in which land is owned by a small number of wealthy landowners, and peasants are forced to work for them in exchange for protection.
- Mercantilism: A system in which the government intervenes in the economy to promote exports and limit imports.
- Mixed economy: A system in which both the government and the private sector play a role in the economy.

Each of these economic systems has its own advantages and disadvantages. Capitalism is often seen as a more efficient and productive system than socialism or communism, but it can also lead to greater inequality. Socialism and communism are often seen as more equitable systems, but they can also lead to lower levels of economic growth. Feudalism and mercantilism have both been used in the past, but they are no longer considered to be viable economic systems.

Ultimately, the best economic system for a particular country will depend on its unique circumstances and values.
