Making one small corner of the world a little bit better is a good thing. There's not much use in complaining that it's not as big of an impact as could hypothetically be achieved on some larger issues.
It's things like this that rob my of my hope for the world.
“He who would do good to another must do it in minute particulars. General good is the plea of the scoundrel, hypocrite, and flatterer.” -- William Blake
