You think the majority of people in Australia are happy? Far from it, you only have to read this website to know that's not true. You think there's a lot of happiness in the US?!
I'd say those people you refer to are happier because they are happy to just to have enough food to eat & a shelter to live under. They appreciate what they have, they're not craving material possessions they can't afford & won't give them happiness when they get them.
