I presume you mean 46.5%. The supposed cause-and-effect that you imply is absolutely false and is unsupported by the study you cited. The continuing problems with the shitshow that is health care in the US is due to things like employers trying to hold down costs against gouging by private health insurers, who are an intrinsic part of the system and in my opinion should not exist at all (Republicans adamantly refused to support the public option, which would have offered an attractive alternative and a path to single-payer). The only small connection that can be drawn between the ACA and higher costs (according to your own cite) is coverage for those with pre-existing conditions – i.e.- a legal mandate that sick people should be provided health care instead of being left to die. Do you have a problem with that? I don’t.
ETA: I just saw that the referenced poster will no longer be with us in this thread, so that will be my last reply to him.
