The chart above illustrates the peak-trough losses (total loss), trough-Q2 2010 gains (total gain), and peak-Q2 (relative to peak) deviations of nominal gross domestic income, disaggregated by income type.
First up, wages and salaries (employer contributions for employee pension and insurance funds and of employer contributions for government social insurance) and private enterprises net of corporate profit incomes grew in sum spanning the recession (private enterprises net of corporate profits includes proprietor's income, which did fall). Furthermore, the drop in wage and salary accruals, -3.6%, was small compared to the drop in corporate profits, -18.1%.
Second, the corporate profit gains during the recovery massively outweigh the wage and salary gains over the same period, 44.7% versus 0.9%. Corporate profits are now 18.5% above the peak in 2007 IV, while wages and salaries hover 2.8% below.
The problem here is, that the deleveraging cycle is heavily weighted on the household sector (the workers at the corporations) - if corporate profit gains do not translate into hiring and wage gains, or even to further capital spending, economic growth will suffer going forward.
Better put, at the very minimum, the recent surge in corporate profits is not sustainable if firms do not distribute the gains to the real economy. Also, meager wage gains does make healthy deleveraging difficult for household sector. Therefore, the recent surge in gross domestic income (hence, it's spending counterpart, GDP) is not sustainable if corporate profits are not recycled.
