Independence Harmful, UN Experts

Can majority of developing countries develop stably? They cannot
UN experts have arrived at sad conclusions while compiling an annual report on human development. Once, the whole of the progressive mankind was very happy that colonies of western countries won independence. Now, at the beginning of the 21st century the gap between average incomes per capita in the First World countries and the Third World countries makes up 75 times (in the early 1960s the difference was 20 times). The share of the national produce on a planet scale makes up 84% for developed countries (70% in the early 1970s), 1.25% for developing countries (2.3% in the early 1970s), Russia's news agency RBC informs.

South and Central Africas are the zone of calamity: the situation is speedily changing for the worse on the continent where mankind once arose. The number of people killed in local wars, ethnic and social conflicts over the decades since decolonization of Africa is higher than over the centuries of slave trade. The living standard in most countries of the continent is constantly declining; the literacy and health of the population is getting worse. 70% of the continent's population is suffering from shortage of water. Life expectancy is sweepingly declining; AIDS incidence reaches 50% in some regions. The South African Republic, the only developed and till recently economically successful country of the region is now turning into a third world country.  

The sad conclusions provoke quite a logical question: can majority of developing countries develop stably? Judging by the conclusions made by the UN experts, they won't develop stably. Unfortunately, the research of the UN experts doesn't provide an answer to the question why the situation is like this.
