This afternoon my six-year-old son and I played the game of Life. In case you are unfamiliar with the game, it's a game in which players move around a board earning money and losing money while following the natural progression of life (getting married, having kids, retiring, etc.).
My son decided he wanted to be the banker. I hestitated on that one, but decided to let him give it a try. He sorted the money his way. When he was done, I looked at the piles. He had all of the hundred thousand dollar bills, while I had all of the promissory notes.
"What's this?" I asked.
"It's life - I have all the money, and you're broke!"
