In many of the oil-rich Arab nations, the immense wealth generated by oil has affected the citizens in the sense they they do not have to seek traditional forms of employment. Many of the wealth is concentrated in the elite circles of society, meaning that many people don't have to work at all. Although this seems like a good thing at first, it is ultimately detrimental to these countries in the long-run, because oil will of course eventually run out.

Smelly rocks sink in water haha!
