Global inequality is caused by a number of factors including population distribution, government policies, technology, corruption and economic growth rates. Global inequality is one of the greatest challenges facing the world today and various governments have taken initiatives to deal with it.
Government policies on issues such as taxation can influence various things including income generation and viability of businesses. This ultimately influences inequality.
Governments that are generally corrupt tend to make it difficult for citizens to acquire wealth or resources necessary to improve quality of life.
Regions with high population densities tend to overuse their resources making it difficult for the people to compete with those in less dense regions.
Regions that are more advanced in terms of technology are likely to be more developed as compared to those without advanced technologies.
