But the real one is from fifties or when? My idea about it was like, ok, we have still men with jobs able to provide for whole family, but on the other hand there is lot of new development in area of taking care about household, so it is not that much time consuming. But I´m not sure if this is correct assumption.

Because we don´t really have such tradition per se. After war when communist took over, every woman had to work, so this never happened here.
