I usually read society and economic books because I am kind of realisitic person and I want to focus on the present and future. I recently red about population especially aging. Over the world, many countries had worsen in aging and loosed power to raise their economic status. It is a big problem not only to few countries but to the whole world. As = For example my country, OECD annouced "Korea is one of the rapid aging country and cannot find to exit of low growth economy." It is a big problem for young people. There are many unemployed people around me. We graduate at the same university and they even went abroad to study English but they didn't get a job and I also work as temporary worker not a regular worker. To solve these problems, some authors recommend to study Asia. Vietnam will be one of the growing because their population is composed of 80% young generation. many manufaturing companies will set a factory on Vietnam then The young labor will boost their economoic status. This means that any countries in the world, Young generation could be the power of growth. And also they said that aging generation is not the same as nowdays. Science makes lengthen our age and to be more healthy so how to deal with old generation is important to a country. They can still work and give benefits for the countries. From this kind of book, I think we also must prepare for the future. In the future, The change is really rapid and we could adapt with it if we have preparation.
