There's the usual slippery slope argument... \:\/

Seriously I think there's definitely a big risk of that happening. Also who gets to determine what's covered by the regular universal health care and what's part of the 2md tier "luxury" treatment? I mean some things are easily a matter of preference and not essential, but I just don't know if I would trust the govt. to decide whether a treatment is too costly to be included in the regular plan.
