The elderly are not a drain, because they can give us wisdom in the time of need, and are good company when feeling down. Also, if you're having a bad day or don't know what to do, you can call/communicate with them (The Elderly) and they could give you suggestions.
I think that the elderly are absolutely not a drain on the community. They are very important because they have been through a lot of things and they may know things that we do not. I don't know why your vote is not matching your argument. The elderly are very important and do not waste resources.
