Rich people do not carry the Yap stones. Servants follow the rich people. Each servant carries a stone on a pole over his shoulder. Today people on the island use paper money for everyday shopping. But for the other things they still prefer Yap stones.
Money has changed over the years: from feathers to Yap stones to today's plastic money or credit cards. Money has become a very important part of our lives. Just look around you and you can see how important it is.
