Your point about not conflating their lifestyles with their financial security is well taken. Their point is not about wealth but about health, not about money but about life. Rather than money grossly gathered, they propose a life well lived.
However, it's important to keep in mind the obverse, which is that one should not strictly dissociate their lifestyles from their financial security. Recognizing that lifestyle and wealth are uncorrelated (or loosely correlated) avoids the facile prediction that overwork will yield wealth when, in reality, overwork most often yields a miserable, dissatisfying life without extravagant wealth.
Agreed, but I find such advice feels weird from people who are extremely wealthy.
It's a bit like if a top chef did a book on cooking healthy meals - it might be packed with great practices, but the advice would come from a place of advantage that could cause blind spots in giving advice to someone with limited access to fresh groceries, a tight budget, and perhaps several dependents with varying tastes.

I can't really disagree as such, but while I'm only one data point (who comes from a non-rich, working class background) I can't think of anyone I know personally who worked really hard and that made their life functionally worse, although I guess dissatisfaction is hard to measure from the outside.
I certainly know people who've reached a certain point and then improved their lives by working less thereafter, but I still think any advice to work less or chill out early in your career is pretty dangerous ground for younger people to consider.
That's a really good way of putting it, something I hadn't really considered.
I still think it's too easy to find people who work so hard they suffer anxiety, sleeplessness, and ill health all while their personal relationships are neglected and/or attenuated.
It seems clear there's a difficult balance to be struck between living well and living large (so to speak) and advice to the young and inexperienced from those who are successful and accomplished should always be judged critically.

From my experience working harder didn't get me any further than not. Everything I've seen in life has shown me that who you know (and even more importantly who you parents introduce know, at least when you're younger) will get you a lot farther than how hard you work.
Company policies are a different topic than personal success.
If my kids say they want to do well in their careers and have a certain level of material success (they might not, which is fine), I'm not going to tell them to work less, entertain fewer meetings with people, to never rush, refuse overtime, etc. Those are luxuries they can choose later in their career once they're on their way.

I agree, but if you don't know anyone (and I certainly did not) then working hard does, in my experience, yield better results than not working hard. It's like going to the gym - if you have the right genetics and body, you have a huge advantage, but putting in the work is better than nothing if you don't.
