@cicerone imposter,
Thanks CI. I wish I could speak with more authority on the relative presence or absence of such problems up here. I will see what data I can find (my sister in law was the director of a group of hospitals here and worked in geriatrics before that, so she'll have a good working knowledge of the issues and situation).
My guess is that regulatory checks and systems down south have been either so seriously obstructed or gutted (by we all know who) that massive opportunity for fraud lays wide open. That other nations don't end up with such exorbitant costs would suggest this is the case.
But let me get back to you.
