According to Oscar Wilde, what is 'the curse of the drinking classes'?

Oscar Fingal O'Flahertie Wills Wilde was an Irish playwright, novelist, essayist, and poet. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s.

One of his well know quotes was 'Work is the curse of the drinking classes'. It is a play on the phrase 'drink is the curse of the working classes' where the posh people would say that people are poor because they 'indulge' too much, forgetting at the same time that the aristocracy and self righteous middle classes drank and ate far too much but of course had the money to do it. He is taking the mickey but it also works because if you like to drink all the time, if you have to work then that work will get in the way of the time you could spend drinking.
