Thomas Sowell writes good common sense in all his articles and books. His article today on RealClearPolitics Cheering Immaturity is an example. I worked at one time at Educational Testing Service, and saw close up the common complaints that "SAT tests are unfair". Of course, the tests aren't unfair - they predict with a high degree of accuracy who will do well in college and who won't. The college curriculum may or may not be "unfair" in what they emphasize and what they ignore, but the tests certainly aren't the source of that "unfairness".
Similarly, some cultures put more stock in hard work and education than others. There is nothing "unfair" about the fact that cultures who emphasize hard work and education tend to do a lot better in the real world than those who don't. Just as there is nothing "unfair" about the fact that the gazelles who run faster tend to get eaten by lions a lot less frequently. That's reality!
