Who is Saeed Saeed from The Inheritance of Loss and what is their importance?

Saeed Saeed is a man from Zanzibar, and the man that Biju admired the most in the U.S. Saeed is very charismatic, hard working and loving of the West. He does all he can, including marrying a white woman, to stay in the U.S. and reap the benefits of being a citizen—including owning many pairs of shoes, though not all of them fit him.
