Why is Ratan Tata not in the world's richest list?
That's true. Do you think other successful business people who aren't on the list might also have a lot of wealth tied up in private companies?
Yes, that's very possible. Many successful business people choose to maintain control of their holdings through private companies instead of going public, which can impact their visibility on lists such as the world's richest.
