大卫·李嘉图《政治经济学及赋税原理》· On the Principles of Political Economy and Taxation · 投资
It has been my endeavour to shew throughout this work, that the rate of profits can never be increased but by a fall in wages, and that there can be no permanent fall of wages but in consequence of a fall of the necessaries on which wages are expended. If, therefore, by the extension of foreign trade, or by improvements in machinery, the food and necessaries of the labourer can be brought to market at a reduced price, profits will rise. If, instead of growing our own corn, or manufacturing the clothing and other necessaries of the labourer, we discover a new market from which we can supply ourselves with these commodities at a cheaper price, wages will fall and profits rise; but if the commodities obtained at a cheaper rate, by the extension of foreign commerce, or by the improvement of machinery, be exclusively the commodities consumed by the rich, no alteration will take place in the rate of profits. The rate of wages would not be affected, although wine, velvets, silks, and other expensive commodities, should fall 50 per cent., and consequently profits would continue unaltered.

白话
我全书想说明:利润率只能靠工资下降来提高,而工资永久下降只能靠工资所购买的必要品降价。所以,外贸或机器进步若能让劳动者的食物和必需品更便宜,利润就会上升;若便宜的只是富人消费的奢侈品,利润率不变。核心是:利润率的钥匙在工资品成本,不在一般物价。所以,判断一项进步是否提高利润,要看它是否降低了劳动者必需品的价格。
上下文
李嘉图总结全书核心论点:利润率取决于工资,工资取决于必要品价格。
今日一问
你关注的成本下降,是降低了普通劳动者的必要开支,还是只让少数奢侈品变便宜?
