I think the point they were making is that the care home and the doctor have a perverse financial incentive to maintain a life beyond the point there’s any quality to that life.

Obviously in a half-way decent society costs shouldn’t be a deciding factor in end of life care or euthanasia decisions for the elder or their family, but neither should rent + fees be a compelling interest in the decisions of those providing that care, yet it’s obvious that it can be.
