A pea-picker is a derogatory reference to poor, migrant workers during the Great Depression.
So the word " depressed " or " wretched " describes the pea picker camp best.
Explanation:
The term "pea picker" is used to distinguish a group as a lower social class from some other similar groups. These people were unskilled, poorly educated workers, employable only in menial jobs, such as harvesting crops and, as such, received poor wages for working long hours under dreadful conditions.
