There is big difference between worth and brand value.
Worth of somebody/something remains same irrespective of place, time, and region; while brand value depends of the quality, intellectual level of investor and more importantly by literacy of the customers, region, and time.
Sachin is like Kohinor whose is invaluable--beyond any brand value.
While mediocre Dhobi is like a piece of glass , which some cunning marketer is trying to sell at unreasonable value because the marketer knows that customers are illiterates.
