The document compares Abhishek Bachchan and Amit Kumar, sons of famous Bollywood stars Amitabh Bachchan and Kishore Kumar. It notes that Abhishek is a famous film star who works consistently and has many hits, while Amit Kumar is an unknown singer who has no hits and does not work. However, it states that Amit Kumar is actually richer than Abhishek because his family receives royalty income whenever songs of Kishore Kumar are played publicly, providing passive income without work. This royalty income from Kishore Kumar's past work makes Amit Kumar richer than the actively working Abhishek Bachchan.
