Something of enormous global significance is happening almost without notice. For the first time since agriculture-based civilization began 10,000 years ago, the majority of humankind is no longer poor or vulnerable to falling into poverty. The Brookings Institution reports:
By our calculations, as of this month, just over 50 percent of the world’s population, or some 3.8 billion people, live in households with enough discretionary expenditure to be considered “middle class” or “rich.” About the same number of people are living in households that are poor or vulnerable to poverty. So September 2018 marks a global tipping point. After this, for the first time ever, the poor and vulnerable will no longer be a majority in the world. Barring some unfortunate global economic setback, this marks the start of a new era of a middle-class majority.
In most countries, there is a clear relationship between the fate of the middle class and the happiness of the population. According to the Gallup World Poll, new entrants into the middle class are noticeably happier than those stuck in poverty or in vulnerable households. Conversely, individuals in countries where the middle class is shrinking report greater degrees of personal stress. The middle class also puts pressure on governments to perform better. They look to their governments to provide affordable housing, education, and universal health care. They rely on public safety nets to help them in sickness, unemployment or old age. But they resist efforts of governments to impose taxes to pay the bills. This complicates the politics of middle-class societies, so they range from autocratic to liberal democracies. Many advanced and middle-income countries today are struggling to find a set of politics that can satisfy a broad middle-class majority. The tipping point in the world today offers opportunities for business but complications for policymakers.
