When I first heard of people saying this I cringed inside. Will Wilkinson, very amusingly, sets them straight.
By the way, Atlas buffs, the point of Atlas Shrugged is not that you are John Galt. The point is that you are not John Galt. The point is that you are, at your best, Eddie Willers. You’re smart, hardworking, productive, and true. But you’re no creative genius and you take innovation — John Galt — for granted. You don’t even know who he is! And this eventually leaves you weeping on abandoned train tracks.I sure as hell am no Eddie Williers, even at my best.
He goes on to explain that his big worry is not people going Galt, but people going Stadler. I hadn't thought of it in those terms, but essentially I've also bemoaned people going Stadler, or just being Stadler. To find out what that means I guess you'll have to read the book.
