If those unnecessarily cheap priced restaurants didn't pay above average salary/wage to employees government must legislate " Prohibit unnecessarily low priced foods unless restaurants' employees didn't get higher salary/wage than the average"
Most of the unnecessarily cheap priced restaurants in Japan are run by elderly owners. They are usually run in old buildings and equipment that have recovered their initial investment. Many owners have saved enough to retire at any time, some hire no workers and run the business as a hobby. This is what happens when restaurants that originally had normal prices are left behind by inflation. ”When the owner retires, it's over.” "Even if it becomes popular and tourists flock to the area, new capital investment will inevitably raise prices." These restaurants are only possible in the miraculous balance of a small community.
