> Compare, for instance, the backgrounds of two elite class premiers: George W. Bush and David Cameron. Bush’s patrilineal great-grandfather Samuel P. Bush established the family’s political dominance through technical education and the management of a firm that manufactured steel railway parts. > In contrast, Cameron’s father, paternal grandfather, and great-grandfather were all Oxford-educated partners in the stockbroker’s firm Panmure Gordon & Co, while another Sir Ewen Cameron was chairman of HSBC. His maternal grandfather came from a family of minor titled gentry and military officers. The differentiating factor between the two major factions of the British elite was whether they derived rents from aristocratic land holdings or professional-class financial speculation. Neither built their fortunes on the industrial basis that enriched the Bush family and many of their American peers. This needs expanding into a full journal article that addresses societal sector representation over time. My hunch says that most developed nations lie on a linear continuum (more elected officials with generational manufacturing backgrounds vs more elected officials with generational finance backgrounds) but I'm only somewhat familiar with political histories of the US, UK, Spain and Italy.
