In which countries is it not cheaper to cook your own food than to buy it out? The only things I can think of are:
- truly street food in areas like sinagpore or india which is not a sustainable every meal option for most digestive systems
- island nations where you're comparing fresh produce to a prepared meal
It should be and is cheaper to cook your own food. Purchases are limited to need, meals are usually a tiny percentage of the overall purchase, cost does not include: rent, talent, fixed costs such as kitchens/tables/plates/etc, healthcare, marketing, etc.
