Yes, because we made it powerful. We don't go to school for education. We go to school to get degree and be able to earn money. Instead of going to school if we learn farming and agriculture we will have food for more people. And we know that there's medicine for everything in nature. We don't need to buy chemical tabs. Even food can be money. You can exchange rice with flour. But this paper money is valueless, only we made it powerful. If economy goes down the paper money wont work. But we still can eat foods and exchange it with other valuables. People are poor because we gave power to paper money. If money was everything there would be no people right now because there were humans before money.
