If they had cooked a full meal, especially for others, they'd realize that you can't prepare a complete meal with only the ingredients that you can see from a window into the bakery, the photo on the menu, or seat at the table.;Each dish requires ingredients that, though of small or of no notice, together, in proper amounts, and at appropriate timing, and with careful mixing, create a delicious and perhaps even nourishing meal.

And as discerning gentlemen (and the rare woman) of education and means, they would recognize how much a good meal resembles a good society. These are a few facts that match both.

1: Every element (ingredient/person) of value to the family is not the "bread winner".

2: Elements (ingredients/individuals) of different sizes and ages have different (nutritional, activity, environmental, educational and other) needs. Some of these individual or combined elements can benefit if these are provided with special training, or equipment, or experience.

3: Sometimes, for full nourishment, for maintenance of stability, proper exercise, and growth, less enjoyable elements must become a part of the meal first - "not until you eat your vegetables."

4. If you do all these things correctly, most often the food goes in enjoyably and well, it nourishes activity, health, and growth, and even the crap feeds plants and useful insects.

It doesn't work if you only consider the budget or if it includes poor ingredients.
It doesn't work if your goals are enjoyed more or only by the bread winners
It doesn't work if there are no fair advancement and enjoyment goals for all the members.
The whole doesn't work. It doesn't play. And it doesn't last.
