by Those who are opposed to life extension technologies almost always argue that it is necessary for some people to pass away due to the world's growing population. However, that theory is flawed, and what will actually happen is that fewer people will want to have children. Japan, Sweden, and Switzerland take the top three spots for countries with the longest lifespans. Having children was less of a priority there due to the fact that people there can live up to the age of 100. Some married couples in those countries have settled for the companionship of animals, also known as fur babies or pets.
In addition, there will still be deaths due to the fact that only the wealthy will be able to afford this technology. Because of the prohibitive cost of life extension technology, the middle class and the poor will continue to perish in the same manner as they always have. Did you know that diabetes can now be treated successfully? Even though there is a procedure called pancreas transplant, diabetic patients continue to pass away because they are unable to afford the expensive technology required for the procedure.
Even if a cure is discovered for cancer, aging, and every other disease, people will still pass away as a result of acts of violence, accidents, and natural disasters. Therefore, there will still be a general decrease in population. Because most people pass away between the ages of 35 and 50, people have always made an effort to have as many children as they can. This is because people's natural instinct drives them to want to have replacements for themselves. Then, as medical science and technology advance, people are living longer.
Because children and grandchildren can compete with you financially if you live longer, fewer people will actually want to have children if they learn they can extend their lifespan. This is due to the fact that children and grandchildren can outlive you. They will eventually wish for you to pass away so that they can inherit your estate, but this won't happen as long as you are still alive because you are 300 years old.
This will decrease the number of "old money" people since they cannot get inheritance anymore.
You know how most of us do not care about our 3rd degree cousins and other far relatives. I can see 200 year old billionaires with long lifespan will not care about their great grandchildren. Yes they are your descendants but the blood is already far. This may sound creepy but in countries where cousin marriages are legal, long lifespan could lead to someone marrying their far ancestors.
The work force will also be more competitive because life extension technology also increases the prime age. A person could still be work at age 90 since aging has already reversed.
