The "unsubstantiated statements" you are referring to comes from sources who are analysing the measure. You seem to know more than those who are doing the analysis and are experts. Not everyone is a "liberal hiding under a rock". 
The measure will go through debate and discussion. It will undergo changes.
The good thing is that Obama started healthcare up where many presidents failed and now we actually will see a version of national health care. Just hoping not too many will lose their insurance. Remember, Trump said it will be better and cheaper. We'll see.
