There is one Iowa farmer who is sitting more pretty than those other CEOs......especially since he sold the rights of his own soybean genetics to Monsanto:
https://en.wikipedia.org/wiki/Harry_Stine_(businessman)
From Forbes magazine: "Farm boy turned seed-genetics savant Harry Stine has become the richest man in Iowa licensing his powerful corn and soybean seed genetics to multinational firms like Monsanto and Syngenta. One of Stine's current projects is gaining traction with corn growers and could revolutionize the corn industry: seeds bred to thrive when they are densely planted, dramatically increasing harvests. Farmers planted 140,000 acres of the corn in 2015. Stine grew up the son of a hardscrabble farmer and began dabbling in seed breeding in the 1960s. Dyslexic and mildly autistic, but a math and data wiz, Stine quietly built some of the most genetically robust and highest-yielding soybean seeds in the industry. He was one of the first to patent the genetics of the soybean in the early 1990s and, as a savvy businessman and formidable negotiator, landed lucrative deals licensing the genetics to industry heavyweights. Stine Seed still reaps millions of dollars annually from these contracts. It also develops biotechnology traits, which are often applied to seeds to make them pesticide-resistant. Stine owns a small home a couple hundred yards from work and drives a Ford F-150 pickup truck to the Stine Seed headquarters, where his four children work as well. He's an avid table tennis player and enjoys hunting morel mushrooms. He donates to his alma mater, McPherson College in Kansas, as well as to the Mayo Clinic."
Clearly not a permie vision, but some savvy nonetheless.
