You don't necessarily need "Mad Max skills" as long as you're part of a group of people.

The ones to dominate in groups tend to have social engineering skills, or "Ben Linus skills" you could call them.

They don't need to know how to start a fire, or fire a gun, or fix a car. They can just get other people to do it for them -- not for money, but because they can con them in to it, or exploit their weaknesses, set them against one another, or bribe them with promises.
