Yes, the UK was right to nationalize Northern Rock in early 2008, because it is a national landmark and an historical site that many people will be interested in for years to come. Nationalizing something makes it valuable and a treasure for all the people the UK to own, and it makes Northern Rock a point of national pride.
No, the UK should not have nationalized Northern Rock in early 2008, because there was more poor impact on the economy by nationalizing it than there would have been if it would have been allowed to fail. By sustaining Northern Rock, the UK used tax dollars to support what were bad business practices. It is not wise governmnent to allow businesses to continue inefficiently.
