For many Americans, the single biggest problem facing the country is the growing wealth inequality. Based on income tax data, wealth inequality in the US has steadily increased since the mid-1980s, with the top 10% of the population currently owning about 73% of the country’s wealth. In a new paper published in PLOS ONE, researchers have quantitatively analyzed several of the major factors that affect wealth inequality dynamics, and found that the most crucial factor associated with the recent surge in wealth inequality since the ’80s has been the dramatic decrease in personal savings, followed closely by a large increase in the dominance of capital income over labor income.

Taking these findings a step further, the researchers showed in their model that reversing these two trends can prevent and even reverse a further increase in wealth inequality in the future. The researchers hope that the findings will lead to policies that reproduce these results in the real world. But progress in this area may not even have to rely solely on policy changes, as the researchers note that the 2008 financial crisis has caused Americans to save more money, potentially bringing an opportunity to restrain some of the growth in wealth inequality.
