That's the other concept in Dark Knight Rises. In this film they seemed to be implying that the gap between the have and the have nots had become increasingly wider. That's why they focused abit on Blake and the orphanage, the charity money from the Wayne Foundation that dried up, Fusion power for all and Selina Kyle whose entire purpose was like a female Robinhood taking from the rich and giving to the poor. That may have been the point of her female companion who look a bit lower than Selina.
While I see this I don't think it was very well told but it seems to be an extremely like perspective given much of particular dialogue pieces.
