We had a lot of national disasters in 2011. Japanese yen is very expensive. Japan economy looks like a bottom in 20 years. However, Japan mega banks hit the highest record of benefit. The reason is clear. They get money from Japan fund interests – which means our tax. However, banks do not pay interests to us. Well… very good and easy benefit. Japan government still needs money until they can raise the tax. However, if Japan funds can become to default, the banks may crash. The money ration to government and private is not healthy. It sounds like we should raise tax or our tax mostly go to banks for their amusement.
