Except the food cost is only a small part of what we are paying for at a restaurant. What we are paying for is the worker’s time and skills. We could, mostly, eat the same ingredients at home for much cheaper.
A lot of the other costs are small and make profit in scale.
There is an unfortunate reality that there is a tipping point. At some point, Europe will need to cede Ukraine and stock up for itself to defend the next Russian incursion.
