Suppose records show that the average income in a country has been increasing over a period of time. From this, can we conclude that all sections of the economy have become better? Illustrate your answer with an example.

An increase in a country’s average income over time doesn’t necessarily guarantee improvement across all sections of the economy. For example, the average income can rise due to increase of salary in a particular sector but other sectors can continue to earn less. Therefore, we cannot conclude that all sections of the economy have become better.
