Why do poverty traps exist ?

When we think of poverty,we often think about hunger as hunger and poverty go hand in hand. We have also been exposed to the imagery of poverty by living in India where the demographic is an extensive mix of the extreme poor and the extreme rich. We are also often caught in a thought process where we think that poverty is something that poor people deserve because of their lack of merit,skills and inability to put in adequate amounts of effort to escape it. In the book ‘Down and Out in Paris and London’ by George Orwell,he questions this aforementioned philosophy through an extensive account on poverty in the streets of Paris and London.
