I absolutely agree that we must know the cost before moving forward with a Medicare for all model. However, since the GOP is not even considering it and they are in charge of all three branches of government, I am sure that the CBO has not even been directed to figure out what the costs would be and who would pay what portion. No, I do not consider someone making above $125k to be wealthy, but it should definitely be a sliding scale based on income. The ACA was kind of like the last election - you have nothing but BS to choose from, so you do the best you can. The ACA was certainly not the progressive Left's choice and it was not the Right's choice, but it was a start in the right direction.
