Deep breath bud. They actually agree with you.

The vast majority of us are in no position to instantly fix systemic problems.

However we do have the power to feed a hungry family for a day. (I'm using your example)

If you and I were walking down the street and you gave your share of food to some stranger because they needed it, id say that small act of kindness was uplifting too.

Does that small act fix the systemic issue that's leading to starving people? No. But at the very least you're acknowledging that you believe it's wrong. You're using the small amount of power you have to fix a fraction of a symptom, for a moment. And that's uplifting.

Its uplifting to know there are good people in the world. Right now they may not have a lot of power. But maybe one day they will. And that's uplifting.
