More young people than the old in a country will lead to more advantages or disadvantages Nowadays in many countries there are much more young adults than the older persons. Though this situation will lead to some problems, I believe the advantages of this situation can outweigh the disadvantages. A country which has a bigger proportion of young adults always has more labors than those country that do not have many young adults. It means that the country’s economy can develop faster with the affluent source of labor. In addition, young adults commonly have more creativity than the old people. As we all know, creativity is a kind of priceless resource which can even influence the entire world. For example, the invention of MOS, by some young scientists, and the relative series of inventions ,such as chip and remote control system ,totally changed the speed and quality of production. Though the old have more experience, the thing that really prompts the development of our society is innovation in which field young adults are the main force. And with more young adults, our society’s medical system will have less pressure, for young adults are always healthier than the old. In that case countries can put more efforts and funds on other fields such education and science. This can bring a essential improvement of livelihood In conclusion, more young adults than the old can provide enough labor and creativity to a country. It will bring more benefits than disadvantages for the economy and people’s livelihood.
