I suppose it's more socially acceptable that the men neglect the family. (Speculation:) Or men tend to neglect more ?
But to me the problem is companies working employees too long. Salary before meant putting in your 9-5 and leaving early on Fridays. Now if I don't put in 12 hours a day I look bad. If I do I look average.
This choice is not gender neutral, we can see clear differences - and this shows up in all kinds of places, choice of profession being one of them; taking time off for family - another.
