DID Mark Zuckerberg, one of the wealthiest men in the world, take a really good look at the Richard Mille wristwatch of Anant Ambani during the latter's lavish pre-wedding ceremony in Jamnagar, a city in India's western Gujarat state where the Ambanis — Asia's richest family, says wealth tracker Forbes — built the world's largest oil refinery? The Meta founder was one of the world's super-wealthy who traveled to Gujarat for the ceremony earlier this month in their private jets, whose total cost could have fed the refugees starving in Central Africa's war zones. Pop star Rihanna, shuttled by a luxury jet, provided the entertainment, with Bollywood stars as the front act.
