I recently read the sun also rises by Hemingway, where the protagonist is living as a journalist in Paris, and takes a few weeks off to travel to Pamplona for the fiesta.

In the novel, Jake (the protagonist) mentions that he has around $2000 in his bank account(I can't remember/find the exact amount, sorry), and throughout the book, despite not seeming to come from a well off family, Jake seems to be out almost every night drinking wine and having a good time.

My questions are: would it have been normal for somebody on a journalist's salary to be able to live this kind of lifestyle in the 1920s? How typical was it for an American or an English male at the time? If not typical, what were the average earnings, and how would they compare to Jake's lifestyle as portrayed by Hemingway?

Thanks for taking the time to read my question
