Should the elderly back away from Acetaminophen?

[quintessentone]

And perhaps the idea of minor pain relief seems to outweigh the liver damage over long term, and that is acceptable to medical technicians.  

Many of elderly who report pain are treated as if they were 'making it up' or 'exaggerating' their pain for attention, and most nursing home staffing situations are far from the nurturing caring facilities they promote themselves to be... what is the single lowest "cost" treatment for pain?  Acetaminophen.  One dose... walk away.

Does it really work? Is it a liver-damaging problem over long term?  Do the administrators and accountants care?  Or do they not likely hold that "They're just "old people" who are going to die anyway... and this is a business... not a charity... our employees and services are not based on love and caring... that's just marketing for investors and suckers customers.

I truly hope that I am completely wrong, at least in some cases, because my Mom spent a lifetime there for a few years before I got her out of there... 
It was horrific, if you care about the actual point of living... as opposed to be in a perennial 'holding pattern' until you die... among uncaring strangers.

Well my mother is properly looked after and there is nothing wrong with her liver and that's after a decade of being given the right dosage of acetaminophen and before that she was popping them at will. Believe me, she keeps asking for larger doses of it and they won't give it to her, hence the introduction of morphine (but very little, and she wants more of that too).
