"These unfortunate patients must die but rather because, in the opinion of some department, on the testimony of some commission, they have become 'worthless life' because according to this testimony they are 'unproductive national comrades.' The argument goes: they can no longer produce commodities, they are like an old machine that no longer works, they are like an old horse which has become incurably lame, they are like a cow which no longer gives milk."
