Schor said implementing a living wage is one way to close the growing socioeconomic gap in America.
"The living wage is a wedge for a new economic movement for justice in our country," she said.
"We believe in a different economic principle [from Harvard]," she added, "one operating for the benefit of the majority of people."
After the rally, Schor said she was pleased with the student turnout. She said student activism does impact the administration.
"I think that the administration notices what students are doing, and there has been a lot of progress because of the living wage movement," she added.
West said he was confident that the University would agree to implement a living wage.
"The administration is going to come through," he said. "I think that [Harvard President Neil L. Rudenstine] is deeply concerned about this issue."
Yesterday's rally took place as part of a national day of action by student labor groups. Activists held events at more than 20 colleges across the country.
