So you never really retire, you are just getting some time off for the family, but two parents are not needed to be constantly in the life of a child, so you can really continue to "work" (as per doing something for the society) but giving priority to the family.
I get what you say, I just don't like the idea that people get with the work your ass of and then live as a rent-seeker.
I know you do not mean it like that, but this is what the normal people understand.
