Charles Krauthammer makes stuff up:
This is not to say that a VAT is impossible in the United States, though it is highly unlikely. A few persons outside of government have proposed one and been thoroughly ignored. But anything is possible yadda yadda yadda.
But this “as night follows day” stuff is typical Krauthammer fear-mongering.
Wingnuts monger fear because fear is what they know.
And if he’s correct, so what?
If the government takes over health insurance, whether through strict regulation (the German model) or direct administration (the Canadian model), or something in between, businesses no longer would have to deal with it directly.
in the big picture, It would not be an increase in spending; it would be a transfer of spending from one area to another, likely leading to a substantial decrease in total spending vis-a-vis the economy as a whole.
