When Light Cost a Fortune
What if I told you that in prehistoric times, creating just one hour of artificial light required 58 hours of backbreaking labor gathering timber? Today, you earn that same illumination in less than a second of work-a 300,000-fold improvement that captures the essence of economics itself. This isn't just about light; it's about how humanity transformed from barely surviving to thriving beyond our ancestors' wildest dreams. Economics isn't the "dismal science" we've been told it is. That label actually came from Thomas Carlyle attacking economists who believed in human equality-not their methods. What follows is the story of how economic forces shaped everything from why your ancestors switched from hunting to farming, to why your morning coffee connects you to farmers across three continents. Life for our prehistoric ancestors was genuinely horrifying. Imagine a world where 40% of children died before reaching adulthood, where life expectancy barely touched 33 years, and where one in seven people died violently. Archaeological digs reveal both compassion and cruelty-some communities carved walking canes and pre-chewed food for toothless elders, while others simply abandoned those who couldn't keep pace during migrations.
