Directions: Answer the given question based on the following passage:
Earning wealth by right means and honest labour is righteousness. But greed, and its impulsion to dishonesty and unscrupulousness, is opposed to what is righteous means. It is opposed to general social welfare and one`s own inner spiritual growth. It is righteousness that equalizes a strong man and a weak man in society. If the restraint of righteousness is not there, the strong will have all the riches, and the weak will be deprived of even elementary human satisfaction; and that was what obtained in the feudal social order, where the haves monopolized all the good things of life and the have-nots were left to live a near animal life. This is what we have to change fully in our democracy, by infusing moral, ethical, and human values in our society.
What is the underlying idea of the passage?
