Yes to this, but at the same time, we shouldn't need the idea of reciprocity in order to help others. Are you okay with being the kind of person who sits and does nothing while other people are suffering? Are you okay with benefitting from their suffering? Is that the kind of person you want to be? No? Then maybe you should fight for the oppressed. Use your voice and your privilege to help others.
