What They Said

“Again and again, somebody had put him at a disadvantage and Casey had responded by removing the dependency. … Whenever something important sat in somebody else's hands, Casey had a habit of finding a way to put it in his own.” — Shane Parrish, The Knowledge Project (Shane Parrish)

Shane Parrish is narrating the life of Canadian industrialist K.C. Irving and sums up a pattern across his career: when the railway or an oil supplier squeezed him, he bought a ship or built a refinery. It speaks to why companies try to own the scarce inputs they depend on.

Again and again, somebody had put him at a disadvantage and Casey had responded by removing the dependency. Irving: Competing off his gasoline, so he soon found his own. The government railway charged him more because Imperial had a refinery, so he bought a ship and eventually built a refinery. Whenever something important sat in somebody else's hands, Casey had a habit of finding a way to put it in his own. But after 40 years of those decisions, Allen had arrived in a province where remarkably little seemed to happen without touching an Irving: Competing. That made it easy to imagine him as some sort of industrial monster. But the stories that Allen collected made it harder. A taxi driver told Alan about running out of gas in a blizzard and being rescued by Casey Irving himself, who stopped his…
