And this is not just because it is a service with a disappearing product. Much of the use value of cooking is not recognized outside the home because it never enters the market place to be measured in value terms. It happens without being measured. It just is. Of course we know that is not true ultimately, but for many people it is true on a daily basis.
Children just eat.
Husbands often just eat. Guests just eat. The cook gets no recognition except for a special occasion. The daily breakfast gets nothing. I think perhaps there is something in requiring cooking that continues this pattern.
