(It will take 5 minutes for a sound wave to reach Mt. Fuji from the camera, since the distance between the two is about 63 miles or 100 km.)
Economists are those who have never worked in a factory or a plant but argue with a straight face modern economy whose wealth is produced in factories and plants.
The key to understanding the modern economy is huge potential of supply mankind has obtained through its scientific, technological, and industrial efforts.
First, you have to view the history of human beings in the following manner:
History of Human Economy
T1: The advent of money economy: Needs are surpassed by human desire.
T2: The electronic revolution: Needs is surpassed by supply potential.
T3: The IT revolution: Even human desire are surpassed by supply potential.
Figuratively speaking, "Needs" are a bow and arrow, "Human Desire" is guns, and "Supply Potential" is a nuclear warhead missile.
Economics must be studied and built in production fields but not in a library, since it is not a book but industrial machine that produces goods, products, weapons, and even harmful substances and dangerous chemical/biological agents.
For example, that is why Russia has still such a huge number of nuclear weapons. Thar is why China has become another World No.2 Economy, leveraging the IT revolution.
In 1930's stupid economists were calculating interest rates to understand and address the Great Depression, in vain. It was only solved through WWII.
Even today, stupid economists are calculating interest rates to understand and address the Great Depression of 1930's only to misunderstand it.
Work in a factory or a plant to understand economy based on modern science, technology, and industry!
Or do you want to fly over the globe, on board an expensive jet plane, checking in an expensive hotel, putting on expensive suits, and shaking hands with bloody and dirty hands of super-rich men or quasi-dictators of the world as if you were so qualified and blessed by Devil?
