I agree with your comments about family-work balance. You are absolutely right.
I still remember a time in grad school when a rather mediocre professor who had a couple too many drinks at lunch berated all the grad students for not working hard enough. He felt we should all be in the lab to at least 1 a.m. About a week later, several of us were there at 2 a.m. and wanted to take a photo and post it on his door with the words, "we are here, where the (expletive deleted) are you?" That said, we really felt sorry for him - his daughter got married and he didn't realize she had a boyfriend. The prof was both arrogant and clueless about much of what truly mattered.
