This is what I have been saying ever since they were working on the ACA. Millions would lose their jobs. That's one reason why single payer is hard to put into place.
Also, the for profit companies will raise a stink, stockholders you know. I thought that they could move to non-profit status, give them a year to reorganize. But how do you placate stockholders? You can't buy them out.
I blame the Congress that passed the HMO Act and Nixon for signing it. Has ****ed up medicine for the masses ever since.
