                                         Poll (民意测验)-People unhappy with the rich
     There is growing dissatisfaction toward rich people, according to a new online poll.
     The poll by the China Youth Daily in co-operation with Sina.com has shown the obvious discontent over
the country's widening income gap.
     Nearly 8,000 people filled in online questionnaires last week, and when asked to use three words to describe
society's rich, the top answers were "extravagant" (奢侈), "greedy" (贪婪) and "corrupt" (堕落).
     About 57 percent of those polled said that"extravagant" was the best word to describe the rich, followed
closely by "greedy".
     However, despite their dissatisfaction, 93 percent of those polled wished they could be rich too, and that
richer people should be "socially responsible".
     Some 33 percent of the people also praised rich people for being "smart".
     Nearly 90 percent agreed that most people in society, including themselves, were willing to speak up for the
poor but were reluctant (勉强的) to take action and actually do something for them. The survey comes into a
heated debate over comments made by a famous economist Mao Yushi, who said he was "speaking for the rich
and working for the poor".
     A report made by the Asian Development Bank last Wednesday showed that China's Gini coefficient (基尼系
数)-an indicator of the wealth divide (财富差异)-rose from 0.407 in 2000 to 0.473 in 2010.
     An earlier CASS (财务结算系统) report said that the richest 10 percent of Chinese families now own more
than 40 percent of all private wealth, while the poorest 10 percent share less than 2 percent of the total wealth.
     The country's income disparity (悬殊) is close to that of Latin America, the report which came out in January, said.
