Can you ‘copyright’ a culture?

An interesting article about the exploitation of the Masai culture by commercial organisations and the move towards protecting a cultural identity.  I instantly thought about the branding of the entrepreneur Levi Roots and its reliance on a certain perception of Jamaican culture.    Likewise, the excruciating ‘Italian’ family adverts for  pasta sauce like ‘mama’ makes, if she made it in a factory in Kings Lynn.

Is there a fine line between writing books that explore ‘other’ cultures and exploiting that culture for personal gain?
