The makers of this cartoon used laborers in England instead of those in Northeastern U.S. most probably to appeal to Northern viewers.
In the 1800s, workers in the industrial Northeast:
- Were often underpaid
- Had to work for long periods of time
The cartoonist here is trying send a message here that enslaved people were treated better than certain paid laborers but because it is the North that they wanted to convince of this, they avoided using laborers from the North as a comparison so as not to antagonize them.
They instead chose British laborers as scapegoats to use to send their false and propagandistic message that enslaved people were treated fairly.
In conclusion, British laborers were used because the cartoonist did not want to antagonize the Northerners as these were the people they were trying to convince that enslaved people were not treated poorly.
