Looking at historic economic data can sometimes be a bit bleak. Over the last five decades wages have been left behind by economic productivity, houses have gone from an essential good to a coveted investment, we are saving less money than ever before, prices for everyday goods have outpaced earnings, the financial industry has become the largest sector in the economy, debt around the world has spiked to unsustainable levels, and inequality has broken new records.

Elon Musk alone recently became the richest person in history, topping even the generous inflation‑adjusted estimates of John D.
