出身对收入分配差距扩大的影响有其内在逻辑,它是一个人所有权的既定影响因素,在自然状态下通过各自的循环累积产生贫者愈贫富者愈富的收入分配格局。政府要想减少由出身造成的收入分配差距,就必须在公共政策的原初制度设计中,考虑到出身不利家庭群体的利益。要在起点上构建机会均等的教育制度,并逐步建立人人都能公平享有的医疗保障制度和养老保障制度。 The origin of the income distribution gap has its inherent logic. It is an established influential factor in the ownership of a person. In its natural state, the richer income distribution pattern of the richer and the richest are getting along with each other through their own cycles. In order to reduce the income distribution gap caused by origin, the government must take into account the interests of disadvantaged family groups in the design of the original system of public policies. It is necessary to establish an equal opportunity education system at the starting point and gradually establish a medical insurance system and an old-age security system that everyone can enjoy in an equitable manner.
