The welfare of a country depends on various factors, including access to education, health, the right to security, low unemployment rates among others.
There are different indicators created in order to effectively measure welfare in a country. The GDP (Gross Domestic Product) per capita, shows the amount of income after it has been evenly distributed among all of the citizens of a country. This, however, does not assess the issue of determining if, in fact, the income is being distributed equally. For this purpose, there is another indicator called the GINI index, which measures the actual equality in the distribution of income among the citizens of a country.
I believe that eyewitness are not a reliable source to solve a crime or problem. Those eyewitness play a major role in the investigation meaning that they have a advantage to change minds. Some studies think that people over the age of 50 years old aren't reliable for testimony. Though, some might think that study accusation is absurd, it may be correct in some ways.
Hope I could help! :)
