Economics has always been rather esoteric for most people. Most people's knowledge of the subject is limited to the law of supply and demand, of which they have the most vague understanding. Any understanding beyond that is usually aligned with their political ideology. If they're conservative, they follow the supply side theory that lowering taxes create more jobs and helps the economy. If they're liberal, they follow the Keynesian idea that government spending projects can stimulate the economy. But there's one important economic principle that even economists today have long forgotten or ignored, at the expense of their discipline. That principle is the law of rent.
Before I lay out the law of rent, it bears mention that "rent" in the economic sense is not the same as what is meant in its common usage. We commonly apply the term to apartments, cars, videos, and various other commodities. In economics, its focus is more narrow. It is applied mostly to land, though it can also be applied to things like natural resources or the radio spectrum. Rent is the difference between what a factor of production is paid and what it would need to be paid to remain in current use. Applied to land, it essentially refers to the profit to be gained by virtue of its ownership. Essentially, land rent is equivalent to land value.
