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
When from the progress of population, land of the same quality as before should be taken into cultivation, to produce the food required, and the same number of men should be employed in producing it, the landlord would have not only the same proportion of the produce as before, but that proportion would also be of the same value as before. Rent then would be the same as before; profits, however, would be much higher, because the price of food, and consequently of wages, would be much lower. High profits are favourable to the accumulation of capital. The demand for labour would further increase, and landlords would be permanently benefited by the increased demand for land.

白话
当人口增长，需要耕种与以前质量相同的土地来生产食物，且投入同样多的劳动时，地主得到的地租比例和 value 都与以前相同。但利润会高得多，因为食物价格和工资都低得多。高利润有利于资本积累，对劳动的需求会增加，地主最终也会因土地需求增加而长期受益。李嘉图说明，地租的长期变化取决于边际土地的质量，而利润与工资反向变动；资本积累会带动劳动需求，最终又推高地租。
