What kind of work do they do? Why do they have to work?
The poor people usually do this kind of work. This is because: (i) They do not have enough money to study and get a good job. (ii) Even if they study and get a degree, they still do not get a good job. (iii) They have been in this job since their great grandparents or even before that, thus they are forced to get into this job only.
