>>22233>cooking at home shouldn't be cheaper than eating outside, there shouldn't be a kitchen in every houseThose are two separate issues. Why it's more expensive to eat outside is because the restaurant has to pay salaries to cooks and waiters, rent, taxes, licensing fees, equipment, etc.
No, there shouldn't be a kitchen in every house. People should have a communal kitchen in the building, and then people from that building have to be paid to work in the communal kitchen. It shouldn't be a free-for-all, the communal kitchen should be run like a restaurant. People can have a kitchenette at home to warm up things, make tea, etc.
