What is implied about England's government when Dickens has Joe tell Pip that Mrs. Joe does not want him to be able to read and write?In Chapter...

In this passage, Mrs. Joe is being compared to the government of England.  By doing this, Dickens is saying that the English government does not want its lower classes to be educated.  Dickens is saying that the government fears that an educated lower class will be more likely to rise up and rebel against the government.

In this passage, Joe (and to some extent Pip) represents the lower classes.  They are to be kept ignorant so they will not want to rebel and so that if they do want to rebel they will be too ignorant to do so.
