D.To add excitement and make the story feel real
To live in a Hooverville it would have been very difficult. Shelters that were extremely uncomfortable and very cold to live in especially during the nights. But also live in the same clothing for such a long time and having no money to be able to pay for clothing, nor would you really be able to pay for food and ration it out to either other people or your family. But, it would be very very filthy.
