Neither would any greater proportion of the gross produce be paid to the landlord, whether it consisted of potatoes, which would feed three hundred people, or of wheat, which would feed only one hundred; because, though the expenses of production would be very much diminished if the labourer's wages were chiefly regulated by the price of potatoes and not by the price of wheat, and though therefore the proportion of the whole gross produce, after paying the labourers, would be greatly increased, yet no part of that additional proportion would go to rent, but the whole invariably to profits,--profits being at all times raised as wages fall, and lowered as wages rise. Whether wheat or potatoes were cultivated, rent would be governed by the same principle--it would be always equal to the difference between the quantities of produce obtained with equal capitals, either on the same land or on land of different qualities; and therefore, while lands of the same quality were cultivated, and there was no alteration in their relative fertility or advantages, rent would always bear the same proportion to the gross produce.

白话
李嘉图说,无论种土豆还是小麦,地主得到的毛产出比例不会更大。土豆能养活三百人,小麦只养活一百人,但工资若由土豆价格决定,生产费用大降,扣除工资后的剩余比例大增,可这部分增加全归利润,不归地租。因为利润随工资下降而上升,随工资上升而下降。地租始终等于等量资本在不同土地或同一土地上产出之间的差额。所以只要土地质量和相对肥力不变,地租在毛产出中的比例就不变。
上下文
李嘉图讨论土豆成为主食对地租和利润分配的影响。
今日一问
你能否分清收入增加时,哪些部分归利润、哪些归地租?
