The rise of income inequality and what it means for your career
One of the most important (though maybe regrettable) long-term trends effecting the outlook of many careers is the rise in income inequality. In countries such as the United States and the United Kingdom, the difference in earnings between the best and worst paid has risen sharply for the last few decades, with the top earners taking a higher and higher proportion of total income. From the early 1900s to the 1970s, income inequality gradually decreased. However, in Anglo-Saxon countries it began to rise again from the late 1970s. The rise was sharpest in the United States, where the income share of the top decile of earners rose from 33% to 48% in forty years, while the share of the top percentile rose from 8% to 17%.1 In Japan and the rest of Western Europe on the other hand, inequality was either steady or rose much more gradually.
Increasing income inequality means a better outlook for many high-earning careers. It may also reflect trends in which skills are most in-demand and useful as technology changes, making it important to understand if you want good career capital in the future. Finally, it may mean the financial rewards of being at the top of a profession (compared to the middle) are increasing, and this means the importance of personal fit is increasing.

In the rest of this post, we’ll look at the reasons economists have put forth for the increase in income inequality, and speculate on whether the trend will continue.
