Some Republicans are talking about trying to keep the "good" portions of ObamaCare, and just eliminate the bad portions.
Dr. Jane Orient debunks this fallacy at, "Saving the 'Good' in Healthcare Reform: a Thought Experiment". She discusses the dangers of keeping some of the "popular" provisions such as "stopping insurers from discriminating according to pre-existing conditions", "guaranteed issue", "affordability" provisions, and "performance incentives".
All of these allegedly "good" features merely impose further economic controls, which will eventually harm patients and doctors.
The proper solution is not to try to "save" ObamaCare, but scrap it.
