The elderly consume the lion's share of social benefits and account for a disproportionate amount of the health care costs. They have become an immense drain and liability on all Western Countries, and are due to consume an enormous and crippling percentage of the GDP of many nations in the coming years. This is not the fault of the elderly, but the fault in the manner in which we care for them. There are less developed countries (Nepal is a good example) who take a community, collective responsibility approach. Our current model of hospitals, care facilities, and bloated unsustainable pension plans and benefits are poised to bankrupt many nations as these things did to Detroit. It does not have to be this way, nor did the elderly have to become the parasites that the western world made them into. Also of consideration is the fact that the elderly elected officials that would promise them gold plated pension plans and benefits at the expense of the young, who will never see such benefits; the elderly deserve to be held accountable to their mistakes, just as they raised their children to believe they needed to be accountable for theirs...
On one hand, it is a disgrace to our parent's and grandparent's generations to say that when they are too old to be productive (theoretically) they should be wiped out. Then also disabled kids and mentally ill people should not be cared for. IT is our duty to care for each human as he was created in God's image.
Yet on the other hand, as cludwg stated, they do drain our society of its resources, yet as he suggested we should take to making a better way to take care of the elderly, and also the handicapped and mentally ill people who are not productive, and not kill them God forbid. Yet saying that old people drain our society is likening them to parasites. We must respect our elders as they gave us our life and the world we live in today, and we cannot cuty the branch we're sitting on.
I believe that the elderly are not a drain on society. They can provide help or information when you are stumped. Also, they can comfort you when you are feeling down or upset. They are there for you when you need them. So no, elderly are not a drain on society.
