Firstly, I disagree with the definition all together. If you say that luxury comes after needs & wants, there would be no such thing as luxury. If you want fifty billion dollars, under your definition, that would not be a luxury. I will copy the definition from Princeton University's online dictionary in order to start this reply off as unbias.
Luxury: something that is an indulgence rather than a necessity
So, by my definition a luxury, and I am speaking from a materialistic stand point, is anything that is not necessary for you to have in order to live. The only thing that you really need to live is food, water, and basic shelter. Everything else in life, believe it or not, is a luxury. Everything else that we have is based on our desire to be comfortable rather than our need to survive. I am the first person to support a limitation on luxury. My position is that whenever your luxury effect someone else basic needs, than your luxury need to be limited. My position applies on an international scale, meaning that if the people in one country have luxury that effects the basic needs of the people in another country, than that luxury ought to be limited. However, I will speak from a more understandable and apolitical perceptive in order to keep from unintentionally derailing the conversation. If you are a parent, you have the right to go out for entertainment, buy alcohol, and blow your money on women as long as the kids are feed, the bills are paid, and any other cost that effect the family are covered (toilet tissue, soap, etc). If the kids are not being feed and the bills are not paid, then your luxury need to be limited or done away with all together.
Luxury should be the result of excess time and resources. If there are not excess time and resources, than there is no luxury (or ought not to be). You would have to be a sociopath to go out and buy an expensive new sports car despite having nothing in the house for your children to eat, and having a foreclosure notice on the door. I tend to believe that the same should apply on the international level in regards to taking exploiting resources from other countries (even though we can survive without them).
Nevertheless, I always turn to the serenity prayer, which goes, "God give me the serenity to accept the things that I can not change, the courage to change the things I can, and the wisdom to know the difference". We have to accept that fact that people tend to care about their own pocketbook and well being rather than the well being of others. It applies to everyone, so as much as I usually throw the blame on the rich, I can't do that and still maintain logic. Even some of the poorest people on earth have the goal of getting all they can get. People are sociopaths when it come to money. For example, Bayers, the company that make the drug aspirin, knowingly sold an HIV infected drug to hemophiliacs patients in Asia & South America after it was rejected by the U.S. FDA for that very reason. Bayers not wanting to lose money, dumps it on the poor Asians and Hispanics, which resulted in many deaths by HIV/AIDS virus.

People will do the most immoral and unethical things for the sake of money. A person once told me that they think I would sell them out for $100,000. That let me know a lot about them. It means that they would sell me out for $100,000 and assume that I think the same way that they do or cherish the same things. Perhaps I could be misinterpreting this person because they didn't tell me directly, but they answer a series of questions about online friends and then the online friends could view the answers (This was a RL friend though, who I happen to talk to online too). They could have been making a rational determination based on society's love for money and the actions that they have taken in the past out of their love for money. Anyway, You can also look at the guy who is running for President of Haiti, Wyclef Jean. I don't know a lot about his character or personality, but he has been accused of embezzling $400,000 which had suppose to go to Haiti's relief efforts.
The fact is that it is likely that greed will always exist and effect the lives of society. We simply have to have the wisdom to know if it is something that can or can not be changed in our lifetime. I am currently approaching the conclusion that it is a problem that we will have to live with.
