think the world owes (one) a living
To believe that one is entitled to financial wellbeing or a comfortable life without having to work for it. Our parents worked every day of their lives to give us a better, more comfortable life, so it isn't a complete surprise that kids of my generation grew up thinking the world owes them a living.
think something/someone owes you a living
If someone thinks someone or something owes them a living, they think that person or thing should give them the money they need to live. Nobody owes you a living — you need to work hard for yourself. He was given everything, and grew up thinking the world owes him a living.
