True. Note that my point was in response to Chenier saying that his city cannot feed itself at 40-50 gold / 100 bushels. Something is wrong with the management of a city if it cannot do so. Either it has too much militia or too much gold is diverted elsewhere or tax rates are ridiculously low, etc. In that case, it's not surprising that a city cannot feed itself with such high prices and do everything else at the same time.
I don't mean to say that in general cities must feed themselves at 40-50 gold / 100 bushels or expect to starve.
