I have heard the term reciprocal altruism to also cover events such as the following scenario: A country exists with a racial divide, let's say blue/green. A blue person abuses a green person. The green person does not fight back, and takes the abuse, knowing they are powerless in the society. A different blue person, blue person #2, attacks the original blue person. This puts bp#2 at legal and physical risk, even though they were never under any threat of subjugation or abuse from the original attacker. Blue person #2 would be said to have acted in a form of reciprocal altruism for the green person. This type of behavior is often seen, even in situations where BP#2 has little or nothing to personally gain, was never at any risk, and could potentially receive large negative consequences personally for their actions. Clearly blue person #2 was also acting in a manner of animosity, that (more generalized) could or not be considered discrimination, economic or otherwise.
