what is the theme of les miserables?

The main theme of this work is that the human condition is
universal, and that all humans are capable of compassion and all deserve dignity. The
lives of the poor and downtrodden are portrayed in a way to show their innate nobility
and strength of character, and even though society at large does not value them, they
believe in their own worth. Their suffering and their ability to cope with int shows
they are just as deserving of respect and dignity as the rich ad powerful in society.
Many of Victor Hugo's works were concerned with the imbalance of power and status
between rich and poor.
