D.H. Lawrence hates a lot of things—men, women, machines, London, Wragby, literature, idiots, modernity—but he hates money most of all. Because, he implies in Lady Chatterley's Lover, money makes people do things that dehumanize them. The problem with money is that once you start using it, you start working to get it rather than working to live. So instead of working at something that will directly help you survive, like farming, and then prancing around the rest of the time in red trousers (seriously), you work at a soul-crushing job to get money to spend at movie theaters and jazz clubs to convince yourself that you don't hate your life. Big words, D.H.
Lady Chatterley's Lover suggests that the practice of working for money is at the root of all modern evils.
Although Lawrence claims to dislike money, the novel implicitly favors the wealthy characters over the working class and poor.
