I have absoluting no interest in "celebrity".
Maybe I should ask why you think that someone should not be responsible for their own actions and be allowed to sort out their own problems.
She was the person who ran up the tax bill, she is the one who needed to deal with it.
Because being declared bankrupt is not going to have any impact on her life (unless she splits up with Hobbit man). There is no punishment, all that has happened is that she has weaseled her way out of paying a lot of money to the tax office. She won't be having sleepless nights worrying about whether she will lose her home or be able to pay her bills.
Morally bankrupt is spot on !
