This is an oddly judgmental way to shout empathy and altruism, but I agree with the basics. Valuing altruism and doing things with the only goal of helping others and not expecting to receive any outside benefit that you can identify is an ideology that is often neglected and misunderstood. The benefit to altruism is at once macro and intensely personal. Contributing to a cultural environment where people are helping one another because it’s the right thing to do, and not collecting debts owed in exchange will lead to a value shift away from objectivism and towards collaboration and progress, because society is stronger when the individuals who make up its fabric are suffering less, having their physical and emotional needs met, and spending less time just trying to keep their head above water and survive, allowing them to have more time to contribute to society in a more complex way than just dragging through some 9–5. It frees up time for creativity and passion and insight. That’s the macro benefit.
The personal benefit is psychological and ethical. Doing the right thing for it’s innate value should fulfill and enrich the life of anyone who values empathy and the individual. There is a unique satisfaction and self respect that comes with knowing that you are acting according to your priorities and values, and making a tangible contribution to the world that no amount of money or power can emulate.
