I once saw a high school teacher lead a simple, powerful exercise to teach his class about privilege and social mobility. He started by giving each student a scrap piece of paper and asked them to crumple it up.
Then he moved the recycling bin to the front of the room.
He said, "The game is simple — you all represent the country's population. And everyone in the country has a chance to become wealthy and move into the upper class."
"To move into the upper class, all you must do is throw your wadded-up paper into the bin while sitting in your seat."
The students in the back of the room immediately piped up, "This is unfair!" They could see the rows of students in front of them had a much better chance.
Everyone took their shots, and — as expected — most of the students in the front made it (but not all) and only a few students in the back of the room made it.
