I guess that Fox isn't explaining that Ryan's whole purpose is to give a tax break to the rich via Obamacare repeal.
The plutocratic party doesn't like the wealthy to pay for anything.
Of course, Trump and the gang are also trying to undermine the existing Obamacare service by encouraging insurers to suppose that its future is uncertain and that they think it is a disaster.
It isn't a disaster now, but bad governance can kill a good programme. And it could use some improving.
