The "grief of institutional abuse" would NOT "pass through the generations" if the elders looking to get more payout would just shut up about it and not place the burden of carrying on old grudges to the kids.
Everyone has HEARD ABOUT IT.   It's been addressed. It's in the PAST.    Stop burdening your own kids.  They are YOUR grudges that you won't let go of .  Leave the kids out of it.
