Where I live, we have a saying.

"Don't put off until tomorrow what you can do today."

~ Master Wu, from Ninjago (just looked this up, Master Wu got this from Benjamin Franklin, that wise old monk of Pennsylvania)

I was passing some houses recently and noticed a neighbor just spontaneously put in a wheelchair ramp to their front door. Afraid, I stopped by and asked who was in a wheelchair now. "Oh no one's in a wheelchair" he said, "this is just what we did."

I was finding a new job once and they were very keen on asking me if I had any medical conditions or stigmas. They said that they try to reserve their spots for people who specifically fall short of other places.

An artist I know once made any work of hers created during the passing of the comet C-2022 E3 ZTF public domain for anyone living in the Southern hemisphere under the belief that the comet which comes only once every 50,000 years would only be visible in the Northern hemisphere, offering a way to make up for the loss (which in the end turned out to be moot, the comet was a dud and still ended up visiting the Southern hemisphere via telescope).

What's your unique or almost unique way of making life less uneven for people?
