I've left work in the middle of the day because my wife was hurt, or not feeling well. I've taken off time simply to take her to the doctor for "moral support" even though she was quite capable of going by herself. Either of us will take a kid to the doctor depending on who it's most convenient for.
It's not the 50's anymore. Most people with good relationships want to spend time together. I don't give a rat's ass if I get 30,50,100 million in 20 years for working ridiculous hours now. I could be dead by then. Right now I want to spend time with my family and that's worth giving up a lot of money for.
