100x in 100years..
Things start to change in your mind when you understand the house didn't get 100 times bigger in 100 years.. neither people got 100 times smaller..
The only thing that changed is the purchasing power of the tool we used to exchange and store our work/time.
100 years later you have to work100 times more, or give 100 times more your saved time in order to purchase the same things.
Insane.
