From Gerald Friedman of Dollars & Sense, who notes:
The share of national income going to investment (net of depreciation of existing plant and machinery) has been declining since the beginning of the “neoliberal” era, around 1980. Since the start of the Great Recession, net investment as a share of GDP has plummeted to its lowest level since the 1930s. This sharp drop in investment comes despite sharply rising profits.

There is almost nothing worth investing in that provides for the outrageous profits capital seems to demand. This problem will only get worse as ecosystems collapse. High profits, fewer jobs is insanity for economies
