Human beings are not an economic problem to be solved! In your mis-guided theory, older people are the reason we have an un-balanced budget. Nothing is further from the truth. If the time comes that we allow people to die simply because of economics we are no longer a democracy.
Our society and economic system was built on the backs of these older people that you are suggesting we let die. These people have contributed $300,000 many times over to society. Many constructed buildings, roads, railways, fought wars, and made our infra-structure what it is today, creating billions of dollars for this country. They deserve every chance! By the way, I am not one of them. I am 49.
