man who started Microsoft, Bill Gates, has predicted that by 2035, there will be almost no poor countries in   world. Today,   World Bank says there are 35 poor countries. Most of   people who live in them are on low or no incomes. Gates said that nearly all these countries will be richer in   next 20 years. He wrote: "Every nation in South America, Asia, and Central America (with   possible exception of Haiti), and most in coastal Africa will have joined   ranks of today's middle-income nations." He added: "When I was born, most countries in   world were poor. In   next two decades desperately poor countries will become   exception rather than   rule." Mr Gates said some countries will still be poor. These include North Korea, Haiti and nations in central Africa. He said   good news was that: "Nearly 90% will have   higher income than India does today." He believes countries will become richer by copying their more successful neighbours. Countries will also benefit from new medicines, better seeds for farmers, and   Internet. Gates said many countries that were very poor just   few decades ago are now doing well. He said China, India, Brazil and Botswana were poor thirty years ago but now have growing economies. He said there was still   lot of work to do and that, "more than one billion people live in extreme poverty, so it's not time to celebrate".
