Here the public side is pretty good and we only have private for Smallsteps. We originally got it as a "just in case" before she was born and then, we have kept it because of all her needs. My own treatment and that for my wife is all public and it is relatively fast for most things. Covid has changed some of that though.
When funded by tax dollars there is a lot of inefficiency and wasted money supporting bureaucracy and administration.
But, nowhere near ass high average cost as in the US. That is crazy.
