The Portuguese coach was questioned on the subject after being named as UN ambassador against hunger with the World Food Programme this week.
"I don't run away from it," Mourinho told ITV News. "I justify that. I try and one of the reasons I find to justify is that football gives jobs to thousands of people.
"Football is not about managers and players. It gives jobs directly and indirectly related to the football industry. There are jobs and jobs and families and children and mouths and football becomes a big industry."
As part of his role, Mourinho will travel to Liberia to witness the effects of widespread hunger.
