Servants and maids where much more common in the past than now, especially among the middle class. Also it was more common to have several generations living under the same roof, so 1-2 people would often be preparing meals for 6-12 people. Today it is much more likely that you have 1-2 people preparing food for 1-4 people.
I strongly suspect that the proportion of people eating a meal they cooked themselves is almost certainly higher now than at virtually any point in history.
