I think the author of the picture tried to get the point of upper class people taking advantage of the less fortunate working class people across by showing the big capitalist man taking advantage of the small working man. The capitalist man is shown big and over weight to represent how greedy and selfish he is with the money he gets. And the working class man is shown small and weak to show how insignificant and worthless he is to the Capitalist.
The author clearly disagrees to the way people in the lower class were being affected by factories and unemployment, he shows this with the image of a small worker being intimidated by his boss. He also seems to dislike the way factory owners and most rich men are making their money, this is shown by the money falling from the worker and by the money bags labeled “Profit from child labor”.
To make this cartoon more persuasive the author could have shown the where the workers live in comparison to where the capitalist live or compare the amount of work to pay ratio of both classes.
