There was an article on him recently about him making some charitable donations. Now I think he was trying to influence the outcome of this legislation.
Al Capone maintained soup kitchens for the poor's "benefit" even as his policies frightened investors away from those communities. All in the name of "public image." Carlos Slim's charitable donations are minimal, relative to his holdings at the nation's and North America's expense. The longer we take to fix the problem, the more lost generations there will be in Mexico that can't buy our exports.
