FWIW, I was fortunate to do a postdoc at Bell Labs in the early 90s. The established and successful researchers, mostly men, would all talk about the sacrifices their wives made so that they could focus on meeting the insanely high expectations of the place in its glory days. It was the custom back when they made their reputations. The younger permanent staff members were leery of this because social mores and the nature of the research environment were both changing. The freewheeling pre-divestiture days were gone by that time and there was a pressure to be relevant to the needs of the corporation. The management still wanted publications in prestige journals and an international reputation by 35 but couldn't say how to do all that while satisfying the relevancy mandate. The stress on the younger permanent staff was palpable but they and everybody else made life delightful for us short-term appointees - it was all the things Universities ought to be.
At the end of each Science Magazine issue is a "Working Life" feature where a (typically) young person writes about problems s/he is facing in launching a career. Work/family life balance is a consistent theme and more importantly an /expectation/ even for those on the tenure-track at high powered places. The times they have a-changed.
