I don't agree with anything she's suggesting, because it sounds like her idea is a culling of eldery people rather than actual euthanasia (in which the person in question is usually choosing to end their life, not being put down because they're "old"). Killing off people once they reach a certain age is like an idea from a story set in a sinister dystopian dictatorship.
We don't have too many old people, we have too many cruel, spiteful pieces of trash like her.
