There's definitely a trap we can fall into where we say "If I accept the premise that ordinary people doing X can make the world better, it must also mean that ordinary people who aren't doing X—or worse, are doing not-X—are making the world worse."
But that's not the case. (1/2)
It's not the case morally, it's not the case logically, it's not the case empirically, and it's not a useful fiction that makes the world a better place.
Most of us are doing what we can, where we can. Some is visible, some not. Some of it is at cross-purposes. Always we could be doing more. (2/3)
