Wealth is not necessarily a bad thing when it has been earned in an honest manner and neither other individuals nor the environment suffered for it.
There is a saying in Tibetan that "at the door of the miserable rich man sleeps the contented beggar". The point of this saying is not that poverty is a virtue, but that happiness does not come with wealth, but from setting limits to one's desires, and living within those limits with satisfaction.
The many factors which divide us are actually much more superficial than those we share. Despite all of the things that differentiate us - race, language, religion, gender, wealth and so on - we are all equal concerning our fundamental humanity.
As human beings we each have a responsibility to care for humanity. Expressing concern for others brings inner strength and deep satisfaction. As social animals, human beings need friendship, but friendship doesn't come from wealth and power, but from showing compassion and concern for others.
