My neighbor did exactly this. His was was given the opportunity to be a CEO of
a pharma company, and so he left his job and stayed home to "father" the
kids so his wife could pursue what she was blessed with abilities to do. Not
for everyone, but in this case, he was able to participate in his boys lives at
a level few fathers get to do, and his wife was able to take on challenges that
will hopefully benefit many many people.
