Carlos Slim tops the list of richest people in Mexico. Slim's mobile telephony business, América Movil, had taken over Telmex and turned it into a privately held subsidiary by 2012. América Movil, through its subsidiary Telcel, controls over 70% of the mobile phone line market and 80% of the landline market in Mexico. In the wake of new anti-monopoly legislation in Mexico, the corporation is preparing to sell assets in order to reduce its market share below 50%.
