It would be good idea to do the same survey in Hong Kong. I like the quote in boldface below.
From The Washington Post :
A study led by Jean Twenge of San Diego State University says that college students are getting more narcissistic.
In an analysis of personality surveys given to U.S. college students during the past 25 years that asked for responses to statements such as "If I ruled the world, it would be a better place," Twenge and the other researchers concluded that there’s been a moderate but significant generational change. In other words, young people today are somewhat more likely to be self-absorbed, attention-seeking and power-hungry.
"You notice it, but you don’t know if you’re just getting old and crotchety," said W. Keith Campbell at the University of Georgia, who was one of the researchers. "The data says there’s some reality to that."
