Yes, I believe that Blake had the power to enact social change. His use of vivid imagery was very persuasive in displaying this little boy's emotion in these hard times. Blake didn't have to explain that the boy was working hours a day at very low wages to express the boy's discomfort. He let the boy create a picture in the readers mind of what that time was like and the struggles of a lower class family at that time. Coming from the upper class though, did Blake really have an idea of what life was like? Or did he use cliches to express the boy's sadness and his alleged "anger" at his parents. I like Blake's use of religion in his poems to express the boys anger towards his parents. He says that his parents are at church praying to a God who has dealt them this hand or that is how I take it atleast. Also that his parents have done nothing for him and yet he has to work day in and day out to make a living for them and put food on the table. This is effective because now as a reader we begin to feel the little boys pain and this society that he has to live in that he has to work at this young age for his parents to still struggle. And this is the imagery that Blake uses to his advantage to hopefully enact some sort of social change.
