Mukesh Ambani vs. Carlos Slim Helu & family

During the Covid-19 lockdown, Ambani raised more than $20 billion selling a third of Jio to a string of investors, such as Facebook and Google. Reliance owns Network18, a licensee of Forbes Media. Ambani's U.S. educated daughter Isha's marriage to fellow billionaire Ajay Piramal's son in December 2018 drew 10,000 guests, including Hillary Clinton. Reliance Industries bought the Mandarin Oriental hotel in New York for $98 million.

Every Sunday, Slim's father would give him a 5-peso allowance and required him to record his purchases in a ledger. Before going into business, Slim taught algebra at UNAM, a university in Mexico City.
