The university is exploiting your idealism to get you to work without being paid enough. You aren’t “in a position to help people”, you are doing a job for an organization with revenues. They could allocate more revenue to accomplish this work without forcing you to work until 1 AM, but they have made the choice that the work is not worth paying for.

That being said, most good people will go the extra mile if they think it can make a difference, but I see too many who take full responsibility on themselves and “cover” for financially-motivated organizational decisions, which in turn encourages the people who make those decisions to cut even more.

That’s a reference to the Blues Brothers movie
