A crash course in changing the world.
Money is very important thing and it's aways uses all around the world. People must have money or they can't live, but there are a lot of demerit of money. The first problem is about alternative currency. It's a currency that can only use in national, state, or local governments. For example, Japanese Yen can use in Japan, but the other country can't use it because it's alternative currency, so if you want to go to the other country, you must change the money to the currency that can use. The second problem is money is difficult to earn. Long time ago, people don't have the money, so they exchange things that they want to trade things that they are going to have. It's very old-fashioned but they can only do like that. But when they have the money, some people can't have things that they want because they don't have money as much as they want. So it can't be equality. If they want to earn money, they need their job, but having job is very hard, so the poor people can't have things that they need. There are many kinds of the demerit of money and we must resolve them.
After I learned about money, I think that the future of the money can be electronic money. It's better for all people and it's very useful than paper money or coins. I think it won't have the alternative currency and it can earn money as much as we have, so electronic money is perfect and it can use forever.
