I believe illiteracy is a negative word. This is because it means unable to read or write. It also means not knowledgeable. This is not a positive thing. When someone is illiterate, it usually means they are not educated and not informed.
Hope this helps! Please let me know if I'm wrong :)
Among the immigrants, the largest occupation group are the Laborers. During the 1800's, a lot of factories and mines were in operation. Immigrants did not have the set of skills and knowledge to enter into certain jobs. Laborer jobs did not require much skill and knowledge and so it was easy for immigrants to get the job.
