The historical factors are incredibly important for a countries development. For example: Western countries like the UK, France and Portugal all set up colonies in developing countries in the 1800's. They exploited countries for their resources and sent them back to improve the development of their own country. This left countries such as the UK to use these resources to improve the development and the quality of life for themselves. This hence left developing countries that were colonised to suffer as they were taken off their resources, hindering their chances for export and developing for themselves. This lack of development then has an negative impact on other aspects, e.g quality of life, education, health care etc... . For example, throughout the 1800's India was colonised by the British and resources like tea, sugar, cashmere were taken and sent back to Britain where they were sold and hence gaining money for the British leaving India unable to sell and export their own resources. The economic factor are also important. Countries like UK, USA and Germany and very economically stable and hence have enough money to spend on improving the development of their country, by improving health care, education and infrastructure. Improving these sectors will then positively impact their economy, as people who are well educated and live longer are more likely to get well paying jobs and hence give back to the economy. On the other hand, a country whose economy is not so good can not spend on all these sectors, they may spend on infrastructure etc... . This means that there are fewer opportunities to improve the development of the country.
