Economy - The most stable definition is the cattle class seats that the airliners offer commemorating the wagon tragedy. Do not expect this to change in the near future as bigger and wider planes become available. Because people flying this class are "peasants, so they won't appreciate it. And if the airlines made economy more comfortable, people wouldn't pay for premium"
Economic Growth - How people were gotten into the illusion of growth and prosperity. And in some parts of the world, something to avoid in future. Like the French high school text book Histoire du XXe siècle, that teaches "Economic growth imposes a hectic form of life, producing overwork, stress, nervous depression, cardiovascular disease and, according to some, even the development of cancer," What is needed is "an awareness of the limits to growth and the risks posed to humanity [by economic growth]"
Stock Market - A religion invented in the 20th century (and many people follow this religion across the globe even today) that offers people heaven they can dream in this life itself. The followers are encouraged to invest and create wealth (in stock market terms). The priests of this religion (called CEO, iCEO, CXO etc.) get to amass a lot of physical wealth using these small investments from the public and have full authority on the money thanks to the divided investor demography.
Insider Trading - The theory goes that people who knows the inside actions of the company should not be allowed to trade their stocks. That protects the ill-informed public from being at disadvantage. It can also be read that you are only allowed to play dice with your stocks. Why am I not allowed to sell my shares if I know the company is going under water? Or why not better limit the number of investors and respect their right of all information? Is Insider Trading really to be blamed?
