The Surplus That Compounds
One jar barely has anything in it. Look what happens to the other one.
Carnegie's whole thing is "the surplus that compounds" — save a little, leave it alone, and it turns into more than you started with, all on its own, over time. Which jar do you think started smaller?
Color in Carnegie and both jars. Count the coins in each one before you color them in — that's the whole lesson, right there in the jars.
About Copper Carnegie
Grew up watching people in his own family work hard their whole lives and still come up short every month. Got obsessed with the gap between working for money and having money work for you, and hasn't stopped evangelizing it to anyone who'll stand still. The copper wire coil that's always on his desk is a deliberate nod to Carnegie's own telegraph-industry origins — the same wire, a very different fortune.
