Japan is known to be the oldest country in the world. Normal people would be surprised that we are living longer, but economists like us see challenges and problems to solve. Japan is an island country also known as the land of the Rising Sun. It is abundant in natural resources and marine life in the sea. Furthermore, the country is classified as one of the oldest populations in the world, despite its disastrous climate which usually decreases the amount of population. One of the reasons for the longevity of the Japanese people's lives is certainly the nutritious diet they consume throughout their lives. Japan is the country that shocked the world that it can develop a healthy aging society through a good diet. Say no to plagiarism.

Get Original Essay In June 2018, I had the chance to attend Meiji University for the summer exchange program as it is partnered with Chulalongkorn University. I went to Tokyo, the metropolitan city, and saw many elderly people living in the city. My professor, at the age of seventy, taught on this topic. Therefore, I began to wonder why Japanese life expectancy is so long? In Thailand I can hardly see people living more than 100 years old, but in Japan it is quite common that people can still walk when they are more than a hundred years old. Marmot and Smith (1989) concluded in their study that the longevity of the Japanese is the result of a good public welfare system and a good diet. This article will take a deeper look at the demographic model from the aspect of public welfare problem which is considered to be a chronic problem. What might be some of the reasons behind Japan's low GDP growth rate over the past decade? I looked at the Social Security tax rate data and it turns out that about 30% of taxes are collected from income. Ten years ago the average Social Security tax rate was 25%. So my question is: why does the government collect higher taxes? Social Security is the main source of revenue that the government can spend on social assistance, public programs, and many other types of benefits that will better the public. Over the past decade, government spending as a share of GDP has reached 40%, which has placed a significant burden on current taxpayers. With Japan's demographic model of an aging society in the future, the outcome would be much worse than expected. To put it in simpler terms, it means that the birth rate is low and the death rate is high, so fewer newcomers will replace the workforce in the future, and the current workforce will shift to an aging society in the near future. due to intergenerational demographic pattern and taxation, future generations face high tax rates due to population decline over 50 years and continuously decreasing (population aged 15-64 (% of total)) . This fiscal incident could be interpreted as meaning that current workers are required to support the elderly by paying a higher tax, meaning that the current and future generation would be worse off, while the retired citizen enjoys their free time with the support of the government. From what I learned while in Japan, I learned that the cost of living in Japan is very high although my Japanese friend also confirmed this. Therefore, not only do domestic workers have to pay for themselves and their families, but they are also forced to help older foreigners, whose population..
