What are the most serious economic imbalances in the United States and the euro zone?

In the United States, income distribution is constantly skewed against wage earners. To compensate for low wages, households are steadily reducing their savings rate, leading to a structural shortfall in savings relative to investment, and a very substantial accumulation of external debt. The most serious economic imbalance in the United States is therefore the skewing of income distribution against wages. In the euro zone, there has been a steady slowdown in labour productivity, which is now falling. This slowdown in productivity is combined with insufficient investment in new technologies, resulting in very low potential growth. The most serious economic imbalance in the euro zone is therefore that technological investment accounts for too little of total corporate investment.
