Best thing a person living in a Socialist society like India, China, Venezuela or Argentina can learn about:

'Spontaneous order'

Especially the definition of it by F. A. Hayek, an intellectual giant of the 20th century.

It gives one this understanding that humans don't require a top-down, violent, coercive authority to make them organise themselves, but can do so by respecting each others natural rights and acting in their self-interests.

It instills in the reader a sense of wonder, amazement and relentless optimism about human beings.
