That's a trick statement

There is no trick. For it to be a trick of the kind you suggest would require that the meaning people take from it is different from the meaning I intend to convey. I do not limit the claim to "statistically insignificant worse outcomes because the 25 million people added are somehow negligible". I mean it like it sounds. I have not particular expectation that the marginal change to the system will be in the negative direction.
