Answer:
Nick thinks that Tom and Daisy Buchanan are careless people who "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"
Step-by-step explanation:
Nick thinks that Tom and Daisy Buchanan are careless people who "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". He believes they are selfish and unconcerned with the consequences of their actions, and that they don't take responsibility for the harm they cause. To support this, Nick cites the example of Daisy's refusal to take responsibility for killing Myrtle Wilson, despite the fact she was the one driving the car. He also notes that Tom and Daisy stay together despite their infidelity and disregard for each other because of their money and luxuries. This shows that Nick regards them as careless and selfish people.
