Pay attention to this man. Carlos Slim is rated #3 on Forbes’ list of the world’s richest people, and gained his fortune primarily by purchasing Telmex from the Mexican Government in 1990, solidifying the near-monopoly position it holds in that country, then diversifying into other Latin American markets and industries.
Señor Slim chides (in a humorous manner) how Bill Gates and Warren Buffett seem to throw money to various groups:

“Our concept is more to accomplish and solve things, rather than giving; that is, not going around like Santa Claus. Poverty isn’t solved with donations. [In Slim’s case, it’s probably solved with BRIBES... ed.] I think that what Gates has done is good, and above all, because he said he would devote full time to this, and half time to Microsoft, which makes time-and-a-half.”

Slim also has what could be considered an outrageous proposal to help cut Medicare costs in the USA: transfer Medicare patients to new treatment centers built in northern Mexico! My first thought about this was “Holy S**T!”
As I said, pay attention to this man.
