Ask HN: Why do boomers love work so much?

There's an interesting trend I'm noticing. Most of my fellow peers (millenials who work in software) kinda dread work in general. We're missing any sense of "higher meaning" and fulfillment and working 40 hours a week seems very dated and uneccesary. There's greater priority over doing impactful things and not being a slave to work. Oddly, many of the other people we work with seem content with working 40+ hours, taking a standard 3 week vacation and just repeating day in and out. Many of them also been with the same company for 30+ years which is insane! What's the generational divide?
