Yeah, it looks like it’s from the article “Nice Guys Finish First!” That article was apparently published in a magazine in 1980, so technically the OP is right, although it wasn’t collected into a book until the following year.
“The Sun Shines Bright” is the book where it was collected, but it was originally published in the April 1980 issue of The Magazine of Fantasy and Science Fiction.
The year is wrong: it’s 1981, from “the sun shines bright”
