It is believed by experts that the citizens are not satisfied if any additional increase in economic wealth in a country that is already reach. Even though the notion of the statement is accepted by few people but not by all. I believe that all human beings in a country are rich, there would be few who are in need.
According to me, a country can be categorized into developed, developing or under developed lands. To segregate it, the authorities check the poverty level in each country. For instance, The United States of America, called a developed nation because the poverty is less that is number of people who suffer without shelter and food are less. In contrast, we could see many beggars at the streets without any basic needs.
On the other hand, nations such as India is considered as developing land, this is because, there are nearly quarter of population are suffering from hunger and without the necessities that required to run everyday life. Therefore, authorities are initiating schemes and trying to become a developed land. However, there are lot of educated youths without proper job or are not able to manage their living with given salary.
To conclude, I think additional increase in economic wealth will increase the employment opportunities and there will be some citizens can improve their well being as government officials will take initiatives to bring in schemes and projects that is necessary for the people. Therefore, there will human beings to support the economic wealth.
