This article is awesome. It touches on some of the points I raised in my recently-published work: The 'Plenty' Book: the Answer to the Question: "What Can I do to Make This a Better World?" (Kindle, 2020).
There are SO many things we can do to make this a better world; what is required is the attitude of wanting to chip in and make the effort to improve your neighborhood, town/city/county, state, country, and, yes, the world.
But it can't be done by people intent on blamestorming others for their own defects of character and personality. Instead, it requires that we recognize that we are ALL each other's brothers and sisters, and that we don't have any people to spare.
