当经济增长的成果可以公平地分配到不同阶层时,这个社会的发展是可持续的,其内部状态是良性的。收入分配不公不仅使收入两极分化,也使收入流动性僵化,也就是说,富人愈富,穷人愈穷,穷人要变成富人的梦想更加遥不可及。如何解决收入分配不公?如何使穷人更有可能脱贫致富,进入更富有阶层?这是当今中国面临的亟需解决的重大问题。 When the fruits of economic growth can be fairly distributed among different strata, the development of this society is sustainable and its internal state is benign. Unfair income distribution not only polarizes income, but also inflates the income mobility. In other words, the rich become richer, the poor are poorer, and the poor dream of becoming rich becomes even more out of reach. How to solve the problem of unfair income distribution? How to make the poor more likely to get out of poverty and get into a richer class? This is a major issue that China is now facing to be solved urgently.
