You asked a profound question.
I will attempt a profound answer.

1. Why is the purpose of society and our role in society?

2. In Singapore every citizen is an economic cog that is part of an economic engine.

3. As he gets old productivity drops and his role in our society is diminished.

4. Hence the despair.

Basically it's the value system of our society. You are measured by your ability to make money
