To add some anecdotal evidence for America: I've always stuck to a hard 10-6 and I have a great career. Any company that doesn't let you trade talent against time is a company that doesn't respect you as a worker or even an adult. Granted, I work in the single American industry that likely respects its workers the most, but I have friends in other industries who believed that working sane hours was impossible until they... Tried it. Obviously working more means you get more done (assuming you don't burn yourself out), so the cost of working less to your career is nonzero, but this is practically tautological, and the stronger claim made here that it affects your reputation beyond its actual impact on productivity is not as universal in the US as people like to complain.
