We all know by now that American money is fiat (worthless as material) so why do we continue to spend money creating something that is worth less than what it takes to make? Money is only valuable as long as we can trade it, and as long as the government still accepts it as a payment. I suppose, trading money is better than trading goods, but that's a-whole-nother post (which I probably won't do.)
Coins are not the same anymore. A penny is not made of copper anymore. In fact, if it were made of copper it would be considered nine pennies in one because it's too expensive now. Honestly, when you see a penny on the floor, do you pick it up and believe you'll have good luck all day? I sure don't. I just keep walking. Could you go to the store and buy anything worth a penny? No.
Maybe they'll slowly get rid of it, like they did with the 2 dollar bill. Which I believe is only made for special occasions these days. I understand it could come in use when you want to spend the exact amount. I do that too. However, I'm sure in the future all "cash" will be gone and credit cards will be our "sticks and stones." Lets save money and start early!
