At any moment some change outside my control could occur and my place in society would change. Right now I'm pretty self sufficient and don't really need the support of others in day to day life, but that can change, and there's nothing I can do about it. Seems like a good idea to use this opportunity to try and improve things for everyone, even if you don't care about others, just in case your place in society changes. (I actually think it's neat if we try to improve things for everyone for everyone's sake tbh but I get there are people that do not have such empathy)
