Making a Seven-Day Weekend Come True

I wrote this book in the hope that a seven-day weekend might one day become a reality. Maybe by the time we reach the point where it could happen, the world will have been plunged into an apocalypse by war. I need everyone to point out errors in my thinking and examples of flawed reasoning, such as examples that are rumors or unconvincing. Also, since I didn't know how to write it, I just threw in a super-civilization.
