Inequality, which is one of the main concerns to UN, can be defined as an uneven distribution of resources in terms of social, income, gender, ethnicity, disability and age. It was identified as the most significant trend in 2015 as it ranked 2nd in last year’s economic outlook. In developed and developing countries alike, the poorest half of the population often controls less than 10% of its wealth. While it is true that around the world economic growth is picking up pace, deep challenges still remain very present, including poverty, environmental degradation, persistent unemployment, political instability, violence and conflict. These are often closely related to inequality.
