Of course, the malaise that so many people feel cannot be reduced to one factor. For example, the rise in inequality has many causes: the addition of 2.3 billion Chinese and Indians to the global labor force, which is reducing the jobs and wages of unskilled blue-collar and off-shorable white-collar workers in advanced economies; skill-biased technological change; winner-take-all effects; early emergence of income and wealth disparities in rapidly growing, previously low-income economies; and less progressive taxation.
当然，有无力感的人如此众多，不能归结为单一因素。例如，不平等的加剧有多重原因：中国和印度的23亿人加入全球劳动大军，压缩了发达经济体低技能蓝领岗位和可外包白领岗位的数量和薪酬；技术革新包涵着技能歧视；赢家通吃效应；原先的低收入国家，其经济虽在迅速成长，收入和贫富差距却也早早出现；税收的累进性有所衰减等等。
