Of course there are going to be huge problems as people live longer, take advantage of exponentially developing medical technology which will prolong life.
To me, the ultimate irony is that older members of society are made to feel a nuisance, especially if they cannot fund their own retirement, pay for their own medical treatment etc., yet successive governments refuse to acknowledge public opinion re euthanasia where 80% of the population favour being allowed to end their lives peacefully rather than live to be very old if that means taking up public hospital/healthcare resources.
There is just so much hypocrisy around this whole subject.
Imo there should be a much harder headed approach to both the start and the end of life. Children born who are clearly going to have to be completely supported, physically, mentally and emotionally for all their lives, should not have their lives sustained at the beginning, and older people who are in their own assessment a burden on the rest of society, should be assisted to a peaceful exit.
