The context is that the Temple University Graduate Student Association (TUGSA) is organizing a rally in support of graduate students and graduate student workers (research assistants and teaching assistants). They perform many of the core functions required to make the university run, but don't get paid a living wage and are limited contractually in how they can supplement their income (i.e., not allowed to take side jobs). Most folks rely on personal loans, credit card debt, or other's support to make ends meet. Temple has the money to fix this but won't on principle. Leaving wages as low as they do disproportionately hurts students from low SES backgrounds and guarantees diversity within college positions stagnates.
