Inequality of wages among workers and inequality of income and wealth among families and households has been rising steadily for the past half-century in the United States and other developed economies. However, the United States stands out for having the most unequal wage and income distributions to begin with and for experiencing the fastest rise in inequality over the following decades. While this has been a long-developing situation and the subject of academic interest for some time, it is only in the last decade or so that inequality has attracted considerable public attention and become a political issue.
