The thing is though the government system has set limits (and Ontario has been terrible at underfunding and cost cuts) so the reason they determine you at 75% can wait two years is because they have enough funds only to do the person before you at 50 mobility. More funds would be less wait, and less of those govt decisions.
The thing with private is you could go ahead and jump the line if you had funds. So it becomes a two tiered system, a poor person with a tumor would still die because they can't pay.
Its the orphan crushing machine problem. Private care doesn't solve why we needed it inbthr first place.
