Answer:
In chapter 9 of The Great Gatsby, Nick makes the moral judgment that Tom and Daisy Buchanan have lost their moral character and that they rely on their money and the help of other people to get them out of the difficulties they get into as a result.
Nick realizes that Tom and Daisy are completely selfish, shallow people who are so steeped in a world of privilege and entitlement that they don't believe they have any responsibility to anyone outside their charmed circle.
Just look at the way they behaved after Daisy ran down Myrtle Wilson. Daisy didn't stop to see if Myrtle was okay or to call an ambulance; she just kept on driving as if nothing had happened. As for Tom, he immediately tried to pin the blame on Gatsby for the road accident, cynically seeing this was a way to get him out of the picture once and for all. Whatever he might have shared with Myrtle during their brief fling, Tom goes out of his way to protect Daisy from the (arguably just) consequences of her.
