Income growth for the middle class in most advanced countries has been stagnant, and employment opportunities have been declining, especially in the tradable part of the economy. The share of income going to capital has been rising, at the expense of labor.
在大部分发达国家，中产阶级的收入增长早就停滞不前了，而且就业机会也一直在减少，尤其是经济中的可贸易部分。收入中流向资本的份额一直在上升，而且是以劳动所得的减少为代价的。尤其是在美国，非贸易经济所创造的就业数量与其在整体经济活动中所占的比例是不相称的。
