60 being more common than 40 is not obvious (it's not even true), and if it were it should not be treated as okay. The downvotes are because OP is trying to normalize workaholism.

He might have had a different experience than you. I too served in uniform, often working (and earning) for more than 40 hours a week. Later, when I managed a team in a different country, the cultural norm there was to work longer hours as well. It's worth noting that while a 40-hour workweek might be standard in some places, others might see norms of 44, 50 hours, or even more. Even in Europe, roles like production management or working in a SOC often entail more than 40 hours a week.
