Smith describes four factors that destroy and degrade “agriculture, the sole source of wealth and revenue of every nation.”
- Soil Husbandry “the neglect of cultivation and improvement”
- Subsidies & Tariffs “the fall in the real price of any part of the rude produce of land”
- Equipment, Seeds & Fertilizer the rise in the real price of manufactures”
- Devalued Dollar, the declension of the real wealth of the society
all tend to lower the real rent of land, to reduce the real wealth of the landlord, to diminish his power of purchasing either the labor, or the produce of the labor of other people.
