From another perspective, you could say Westerners are people who don't let others have the best of them and bring them down. That they have incredibly high expectations and standards. That they don't take no for an answer. And they will assert themselves and their rights strongly, vocally and openly. Or in other words, give me liberty or listen to me ask for it until I die. Now the question becomes, how much is this attitude responsible for all the richness you described? If it is partially or fully responsible, then others should adopt it as well, and they'd be better off "whining" as well. Let's give a scenario, two kids at a table, one shouts "I demand desert". The other responds "Stop whining, I didn't even get to eat anything, at least you got an entree". Whose most likely to get what they want? Maybe the other should have whined instead: "And I demand a full meal!"
