Part 3: Rejecting Inequality
This is the third part of a three-part series. In part one of this series, I discussed different types of inequality and which ones we should be concerned about. In the second part of this series, I discussed balancing inequality. You can find part two here.
There is a widespread but mistaken belief that great progress across a range of metrics has coincided with rising global inequality, but in fact the data on the Inequality of Human Progress Index (IHPI) created by me and Vincent Geloso clearly shows a global decline. inequality. That’s true for a variety of metrics, including income inequality, education inequality, and most importantly, overall inequality. In fact, in all but two of the inequality measures we analyzed, the world has become more equal since 1990.
Global equality has increased steadily since 1990 in life expectancy, Internet access, and education. The balance of political freedom has improved steadily since 1990, although there has been a slight and worrying deterioration in recent years. That latest reform does not reverse the long-standing trend of expanding access to political freedom but is a reminder that progress is inevitable and irreversible. Political freedom can be lost if it is not protected. Globally, incomes have been relatively low until the mid-2000s, but income equality has improved significantly since then. With respect to food sufficiency, the trend line has been variable, with a trend toward greater inequality in the early to mid-2000s. However, the long-term trend has been one of positive gains in nutritional equity, as the availability of adequate food is more common around the world.
What about these two qualities? The two indicators in the index show the upward trends More inequality: deaths caused by outdoor air pollution and infant mortality. As for the death of air pollution, it may be the result of continued economic growth. Economists talk about this with reference to the Kuznets curve for the environment (created by Simon Kuznets), which predicts that pollution will increase along with economic growth until a critical threshold is reached where pollution decreases. The growing disparity in deaths from outdoor air pollution may indicate that some countries are in the middle of this transition. Those developing countries will likely benefit from environmental quality similar to that seen in today’s rich countries as they grow richer.
Regarding infant mortality, it is important to remember that in reality, infant mortality has decreased worldwide. The growing inequality in child mortality outcomes may be due to the fact that the decline in child mortality in high-income countries has outpaced that in low-income countries since 1990. their first year of life, progress since 1990 appears to have occurred relatively quickly in high-income countries with access to advanced medical technology.
These differences are important but what we find more important is that overall inequality is low. In fact, compared to the inequality trends in previous inequality indices, which examined a few dimensions, the IHPI shows a much greater degree of improvement in global equality. This result suggests that the old indicators tended to underestimate the extent to which development has increased everywhere, and the share of improvements in living standards that have reached the world’s poorest people. Global equality has grown faster than many realize.
In Adam Smith’s day, for every very rich person, there were at least 500 poor people. The inequality was extreme. The increase in wealth since then has made even ordinary people today rich beyond 18th dreams of the century. In the past few decades, the world has become better, again those benefits are widely shared. Increasing public awareness of the decline in global inequality may strengthen support for the free enterprise and free international trade programs that Smith advocated and which brought absolute poverty to record lows and made people around the world more equal.
