This book talks about application of economics theory. Although we are using consumption driven economy right now, we will no longer be able to afford using it because of having dual purposes of both economic prosperity and our survival. Here I am proposing both conditional free economy and conditional democracy as a transitional process to CIRCULAR ECONOMY proposed by Ms. Ellen MacArthur. Since our environment has been changed, we have to change ourselves including our whole systems accordingly. Note: this book has some formatting issues when converting it into Kindle format and thus it may not look very good at some parts of the book because of inappropriate indent spacing; however, I decided to go ahead for publishing it due mainly to time constraints, I am afraid. The contents themselves are fine, though. I am pretty positive that you will find some important information and considerations for our future. Also if you plan to take a macroeconomics class in the future, this book will definitely help you to grasp the whole picture of economics theory very quickly. Since I did not write this book for money, I tend to believe that you will find lots of useful and practical knowledge and information for your benefits. If you use these cleverly in your everyday life, you can definitely take advantage of your dealings in my opinion.
