To me the entire article seems to be establishment propaganda that tries to convince people that the current system is working fine and we just need to dump more money in it, which is not a real solution as we don’t have infinite money. Keep in mind a reform doesn’t mean we automatically turns into the US overnight. It might not even include any private component at all. But any reform that cuts waste will impact the various interest groups benefiting from the waste and inefficiencies in the current system and that seems to be what is article is defending against.
