An iceberg made almost totally of greed,
A greedberg ?
Recorded human history is about 3000 years, but industrial civilization is only 200 years old. (The first railroad ticket was sold in 1808; that's a good starting point for deployed industrial technology.)
I prefer to use the first deployment of the steam engine as a starting point, which pushes it back to 300 years. By 1808 the steam engine had been in wide spread use all over England for nearly a century, and Watts patent was expired.
The reason why worry kills more people than work is that more people worry than work.
