Why do we need bigger kitchens

the beam used to be a wall

I've been watching the Victorian Kitchen series as well as the Kitchen in Wartime series. It's got me thinking. In earlier days, they cooked at home more than we do and they had fewer convenience foods. They also generally had larger households. So I would say they spent more time in the kitchen cooking than we do.
I live in a 1920's house that has had its kitchen expanded to fill what used to be two rooms. And yet, though I have a bigger kitchen than before, my house had a lot more people living in it then than it does now. Old kitchens never seem to be big enough for us these days. Why is that?

I've been giving it some thought. Some of it is fashion, I think. Some of it is that we cook more differing cuisines and so we need more kinds of ingredients and special equipment. What else?

When I was young my mother had certain things on certain days. On wash day, we had bean soup (clothes washing was a big deal with a ringer washer that had to be pulled out, along with its rinse tubs and then there was dragging everything out to the clothes line. Etc, etc). On Sundays we almost always had fried chicken with mashed potatoes and gravy. I know we had pot roast pretty frequently. I don't remember what else. The point here is that it took less thought and less equipment to cook, I think. Though not less time.
