'The Great Gatsby' first thoughts on Nick Carraway

Nick Carrawy is the narrator of 'The Great Gatsby'. He begins by letting the reader know of something that his farther told him while he was young - 'Whenever you feel like criticising people, just remember that all of the people in this world haven't had all of the advantages you've had.' This makes me think that Nick has been raised with a great deal of consideration and rarity. His farther appears to be saying that he has been very lucky to have access to luxuries that apparently not a lot of people around him will have had.

Reading this, there are a couple of questions in my mind already. What kind of special treament has Nick had? why does it make him special? He goes on to give a further reflection of his life, which involves graduation 'from New Haven in 1915' which is a top university in America, which suggests that he had a wealthy up-bringing. He also notes that 'life was beginning over again with the summer' when he gave direction to man looking for West Egg Village, which creates the impression that Nick's recent past had began to shed away.
