The ideas of individual liberty, natural rights, natural law, economic freedom and free market capitalism are not 'western', 'american' or 'european'.
They were discovered and articulated by people using their reasoning faculties about what an ideal social, legal, political and economic order ought to be.
The origin of these ideas is the human faculty of reasoning about the world.
Rejection of these ideas on the grounds of race, culture or religion is intellectual laziness that can certainly be termed as stupidity.
Additionally, imposing these ideas by force, like the colonials and americans attempted, will not work but for a short period.
It has to be a bottom-up, voluntary and spontaneous phenomenon that starts from the individual. You can't force a person or his society to be free and rich.
