Okay, sure, but how much of the population is this awful and does it actually matter since they can't consent to someone else's suicide anyway?
I don't think this is as much of a widespread issue as its made out to be, to be honest.
My brother likely exploited his power of attorney to accelerate our mother's demise and may have injected her with insulin to get the job done. So there's your first datapoint.
What's definite, however, is that he made ~75% of her estate vanish into thin air before throwing her into a low-end nursing home where he wouldn't pay $6/day to have her bathed so she died in her own filth. Nevermind she had a 6-figure pension and longterm care for life. He wanted her gone because dementia had made her unmanageable to him yet he wouldn't let her go to live with any of her other children because he feared he would lose control of the estate through his PoA.
And because he had that PoA, no one could dispute his choices in time to save her. The courts and Adult Protective Services were useless bordering on complicit. The day we finally got a positive court verdict was absolutely 100% coincidentally no connection whatsoever you see 2 days before she suddenly passed.
Lesson learned: when you grow old, don't give anyone on the inheritance train any sort of PoA or they'll instantly become a PoS.
