Sufficient and sustainable well-being of all Thai citizens has been the main government’s objective for national development. Whether it is about the good health of the people or the countrys economy. The main goal of the government is always to assure that everyone can live happily without torment no matter which state in life they are; working or retired everyone has to be able to live comfortably. That is why the government allocates state welfare to the people continually throughout many forms such as 30 baht for all medical care & treatment project which involves the treatment of all diseases for all Thais. And the living allowance for the elderly etc. These things that the government gives to the people for their well-being are good solution. But it would not be good if the allocated budget has to increase every year due to the number of the retirement age population that has increased more and more over the years and causing the government’s initial projects to cross way the actual needs. Despite the governments policy to support the elderly in reality of the welfare of the state to care for the elderly seems to be quite inadequate. Some says that it is not enough for sustenance and claim that the elderly pension do not meet the actual expenses in their everyday life. To summarize many have agreed that the support for the elderly is too little in most peoples eyes. So it is only logic to focus in finding the real need of the living for the elderly population. At present it can be seen that the elderly population is increasing but they are still unable to sustain themselves. There is also a problem with managing their life plan in retirement to be effective and sustainable because most of the population still lack in knowledge and understanding for effective preparation for retirement and causing some people to feel that they do not have enough support regardless of whether government agencies provide state welfare or not.
