“The Kochs were unusually single-minded, but they were not alone. They were among a small, rarefied group of hugely wealthy, archconservative families that for decades poured money, often with little public disclosure, into influencing how Americans thought and voted. Their efforts began in earnest in the second half of the twentieth century. In addition to the Kochs, this group included Richard Mellon Scaife, an heir to the Mellon banking and Gulf Oil fortunes; Harry and Lynde Bradley, midwesterners enriched by defense contracts; John M. Olin, a chemical and munitions company titan; the Coors brewing family of Colorado; and the DeVos family if Michigan, founders of the Amway marketing empire. Each was different, but together they formed a new generation of philanthropist, bent on using billions if dollars from their private foundations to alter the direction of American politics.” HeirsArchconservatives Book:Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right Source: Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right
