From the Guardianship Chronicles

is this tale of alleged abuse of somebody extremely well-known.

When there's money involved, people can act like assholes.

Mrs. Astor is supposedly in all but a "vegetative state," which justifies somebody allegedly treating her like shit.

More:

According to court papers, Marshall:

# Cut back on everything from her doctor visits to the brand of makeup she uses.

# Won't give Astor a hospital bed fitted with rails, even though she has fallen from her bed.

# Ordered her aides to not buy certain medicine at the drugstore because a weaker version is available for less on the Internet.

# Wouldn't allow nurses to buy his mother a new outfit for her 104th birthday.

Sounds like a very devoted son indeed.
