As Mexico’s wealthiest man by far, Slim flies under the radar more than you might expect, considering he’s involved in hundreds of companies in Mexico, which is also known as “Slimlandia.”

Slim’s influence is far-reaching in Mexico and abroad. Bloomberg estimates Slim’s net worth to be at least $58.1 billion, but he could be worth as much as $62.3 billion, according to Forbes.

Despite his wealth, Slim lives a relatively frugal lifestyle; he’s lived in the same six-bedroom house for more than 40 years.

Though Slim is known best as the chief shareholder of America Movil and the founder of the Grupo Carso conglomerate, his riches also result from many other business ventures. Slim spent much of the '60s, '70s, and '80s building a diverse portfolio that now dominates the Mexican economy.

Slim has a clear strategy for making money: He acquires struggling companies and transforms them into multibillion-dollar holdings before selling his stake at a profit. In particular, he took advantage of the Mexican debt crisis in 1982 in order to purchase many deflated companies.

We saw Slim's strategy firsthand in the US in 2009, when he loaned $250 million to The New York Times at a 14% interest rate. Slim saw the deal as a business venture, rather than a foray into journalism.

But Slim announced in 2017 that he would sell almost half his shares by 2020 and in 2018 alone, he sold at least $86 million worth of his shares.

Slim first entered the international spotlight in 1991 when he appeared on Forbes' billionaires list with a net worth of $1.7 billion. The previous year, he saw his first big success when Grupo Carso went public and led the privatization of state phone company Telmex.

"He controls most of the mobile phone, landline and internet markets," Feike De Jong wrote in the Guardian. "His telecoms company, Telmex, installed the city’s surveillance cameras.

In fact, Slim has no need to cater to public opinion; his wealth has granted him political influence to the extent that, for the most part, the Mexican government turns a blind eye to the dominance he has over the telecom industry.

Despite his critics, Slim states that since becoming a billionaire, he has "more activity, more responsibility, and more compromise … The compromise is the challenge of solving Mexico's problems. I’m trying to make our country better in the areas that I can."

Slim says one of his biggest goals is alleviating poverty, and that it needs to happen at the institutional level. "Poverty isn’t solved with donations," he said. "The establishment of business is more beneficial to society than going around like Santa Claus."

Tim Padgett, who interviewed Slim for Time magazine, said, "Just by looking at him, you would never know he is a billionaire." Slim has lived in the same six-bedroom house for 40 years. He indulges in only two big luxuries: Cuban cigars and art collecting.

After his wife's death, rumors circulated of Slim's subsequent romances, most famously with Queen Noor al-Hussein of Jordan. Both Soumaya and Queen Noor's husband, King Hussein, passed away within one day of one another in 1999. Ten years later, newspaper outlets reported that Slim and the Queen of Jordan had formed a close relationship that included jet-setting around the globe and dining in secret at friends' houses.
