Nowadays, rating of old people in many countries are increasing. While people consider pros and cons of this trend, I am of the opinion that the drawbacks are more concerned.
Raising life expectancy has many advantages. First of all, the experiencing of old people are more useful which help for economic, teacher education, architecture. If old people join in company or incorporation, they will give some costly advice. Second, following the increasing of age, the quality of life and medical facility are go up. Government cares more about living standard and also spends more on medical establishment.
In other words, we can see many advantages of population aging however. It can not be denied that old people are the burden in family. Specifically, old people often have some disease about viscera or musculoskeletal system which cost really much for curing and medicine. While, just a little number of old people can make money at that age. Furthermore, government have to spend on the elderly money called state fund supporting their lives. As a result, if there are more and more old people, state fund will be gradually exhausted.
To my mind, life expectancy will be continue increasing and still be the challenge for society.
