They Were Careless People Tom And Daisy?

In the novel, Fitzgerald uses the characters of Tom and Daisy Buchanan to illustrate the theme of carelessness, something which many of the upper class in the 1920s were well known for. Tom and Daisy present their reckless lifestyles through their foolish choices as they lack good judgement and sense and Gatsby too takes part in this with his lavish lifestyle. Fitzgerald reflects upon how the rich members of American society had the freedom to be irresponsible and negligent without the worry of consequences.
After Myrtle, Gatsby, and George died, Tom and Daisy are not punished for their recklessness, but rather rely on their money to avoid responsibility and fix all their mistakes. Gatsby’s neighbor and close friend, Nick, recognized what money had caused in their community. “I couldn't forgive him or like him but I saw that what he had done was, to him, entirely justified. It was all very careless and confused. They were careless people, Tom and Daisy — they smashed up things and creatures and then retreated back into their money or their vast carelessness or whatever it was that kept them together, and let other people clean up the mess they had made”.
Their wealth and ability to blame others and have the freedom to leave is Fitzgerald's way of trying to explain how the upper class must not abuse their privilege and they may live a careless life from time to time but they must not constantly live under the influence that only their lives matter or else they will end up with bad morals, just like Tom and Daisy and people who they may have cared for (Myrtle and Gatsby) will suffer the end result.
