Billionaire philanthropist and the founder of Microsoft Bill Gates finds the term \u2018developed\u2019 and \u2018developing\u2019 countries to be meaningless, but continued to use them in public until now, due to lack of an alternative. \u201cAny categorization that lumps together China and the Democratic Republic of Congo is too broad to be useful. But I\u2019ve continued to use \u201cdeveloped\u201d and \u201cdeveloping\u201d in public (and on this blog) because there wasn\u2019t a more accurate, easily understandable alternative\u2014until now,\u201d Bill Gates said. However, now he seems to have found an alternative. In his recent blog, the second richest man on the planet, shared a new framework to think about the world. Inspired by Hans Rosling\u2019s latest book- \u2018Factfulness: Ten Reasons We're Wrong About the World\u2014and Why Things Are Better Than You Think\u2019, Gates said that people can be divided into four income groups of Level 1, Level 2, Level 3 and Level 4. Gates notes that the largest number of people live in Level 2. \u201cOne billion people live on level 1. This is what we think of as extreme poverty. If you\u2019re on level 1, you survive on less than $2 a day and get around by walking barefoot,\u201d said Gates, adding few more attributes, such as the people in the group probably cook their food using fire, and sleep on the floor. According to Gates this framework helps to capture the nuances of progress in the world more succinctly. \u201cIt\u2019s hard to pick up on progress if you divide the world into rich countries and poor countries. When those are the only two options, you\u2019re more likely to think anyone who doesn\u2019t have a certain quality of life is \u201cpoor,\u201d observed Gates. Sharing more insights from the book about the various levels, the author compares the instinct to label a quality of life below as certain level to \u2018poor\u2019 akin to standing on top of a skyscraper and looking down at a city. \u201cAll of the other buildings will look short to you whether they\u2019re ten stories or 50 stories high. It\u2019s the same with income. Life is significantly better for those on level 2 than level 1, but it\u2019s hard to see that from level 4 unless you know to look for it,\u201d Gates writes the author as saying in the book. Gates noted that the four levels are just one of many insights in Factfulness that will help you better understand the world.
