A century ago Henry Ford showed you could be a genius at business, and a brilliant pioneer in engineering, but a dangerous fool in relation to politics, admiring and admired by all the wrong people. Elon Musk is following in his footsteps – this week giving $75m to the campaign of a man, who according to the head of the military when he was President, is ‘fascist to the core’. I can't tell whether Musk is wholly cynical or a political fool. Luckily Ford’s politics had little impact in the US. But in that respect I fear history won’t repeat itself.
