Beyond learning that all economics truely is about applying complex equations to the simple concept of supply and demand. My micro-economics textbook startled me by proclaiming:
“Rational self-interest IS NOT the same as selfishness. Self interested, but unselfish acts help maximize the givers’ satisfaction as much as any personal purchase of goods or services. Self-interested behavior is simply behavior designed to increase personal satisfaction, however it may be derived.”
Therefore, what ever is going on in the world today economically is driven by 3 forces: Supply, Demand and Rational self-interest!
