Name: Carlos Slim Helu
Net worth: £34.2bn
Hourly wage of average worker: £4.59
Number of years to earn billionaire’s fortune: 3,894,630
The former richest person in the world, Slim’s fortune stems from a vast range of interests held in his conglomerate Grupo Carso. His companies reportedly account for around 40pc of the Mexican stock exchange.
Although the average hourly wage is higher in Mexico than in China, it would take just under four million years to match Slim's fortune. The entire population of Mexico City, Mexico’s capital, would have to work for over four months to earn enough to match his fortune.
