The global economy is new, so much has changed

4 generations ago most of the food that people ate grew within 20 miles, now a good chuck of my food is grown on four continents in dozens of countries.

This and every single thing in my house and car has supply lines stretching over a million miles when the travel of every single item, and their materials are added up. Literally, tens of millions of people helped make my items

Banking is literally hundreds or thousands of times more complex than in my grandfather’s time.

And my entire career is based on technology and infrastructure I read only hints about in science fiction books as a kid.
