Re:, "we will live to be 100 years old". Who will feed us?
live to 100 years old, this is a real problem for the elderly. But for twenty or thirty year old young people, this is too long, far from being able to imagine what this means. Many people may find it so boring to live so long, but in general, this is definitely a good thing. People always want to live longer, have more time to enjoy life, and stay close to those who are close together. Retirement and pension are of course inevitable topics. Young people often do not think much about this problem, but the problem is precisely that the longer the life expectancy is, the more serious the problem is, and the sooner we need to prepare for it.
why is it? First, as life expectancy increases, health life expectancy will increase - but this largely means that the "lingering" year also increases, and the progress of medical technology will allow you to prolong life in unhealthy conditions, which means more diseases and health burdens. Second, the number of years of work may increase. And don't say the problem of forced delay in retirement, even if you are willing to extend the number of years of work, such as work to 70 years old, to maintain the life, but then do you really get to work? Numbness, fatigue and lack of competitiveness are all problems.
generally, people expect technological advances to solve problems, especially expected artificial intelligence and robotics, and expect this change to change the face of the entire human society. But the prospects for this area are rather unpredictable, and not all expectations can be placed in this regard. What most people can expect is that there is no problem for the state and society to support you, but the medical and nursing needs of human services may still be very scarce. We may wish to imagine the state of the big cities in China - the median age of the population in Beijing and Shanghai, which was 42, 47 years in 2010. In 2015, it was up to 44 and 50 years old. How many years would this figure be changed? How many elderly people will expect a young person to serve them? The problem can be said to be more difficult.
hope that technological progress can not solve the problem of
so for each individual, the appropriate choice is to increase their wealth and social resources as far as possible, to leave ample margin for their later years, and to do a good job of planning. But considering the large increase of life span, this difficulty can be greatly improved.
a lot of people can live to 100 years old, and what
for the whole society and policy makers is the best if everyone can add their own wealth and social resources well to their retirement, which is of course the best - but for a community, whether according to the "28 law" According to the limitation of the general resources of society, such a beautiful assumption is impossible. In fact, a substantial increase in per capita life expectancy is likely to increase the overall burden of society, and the resources, whether overall supply or specific distribution, are a big challenge to this situation. One of the challenges of
is that the pace of long-term growth is slowing down. According to the world economic forum's report, in the last ten years, the rate of return on long-term investment has been significantly lower than in other historical periods, the percentage of the stock is 3~5 low, and the bond is a percentage of 1~3. This means that the world's labor productivity has been increasing slowly and the overall wealth growth of society has slowed down. Without the new technological revolution, the burden on the elderly will become heavier and heavier.
