I've read thousands of books. There are good novels everywhere, and no country has the exclusivity of any theme.

> One is the depiction of desolation and human loneliness before the American continent was developed into a prosperous land.

Of course, classical European literature didn't focus on the American wilderness. Though the most famous book on this theme is probably Defoe's Robinson Crusoe. And I enjoyed T.E. Lawrence' Seven Pillars of Wisdom which most people know through the film; the Arabian desert was a good place for loneliness in the wilderness.

> Another is the pursuit of the American Dream, where people achieve success through relentless struggle.

Like wise, the American Dream is an American myth, which is rarely the focus outside of the USA. But searching success through relentless struggle is a frequent theme. For instance, Stendhal's Le rouge et le noir or Maupassant's Bel-ami. These are from two of the most famous classical French authors, but there are many novels about hard-working people that reach success.

> The third is what this novel expresses: what happens after success? Money and career cannot solve all problems; people need more to fill an entire life.

As you like Russian literature, I suppose you've read Goncharov's Oblomov and Chekov's theater, especially Uncle Vania. That theme is central in one of the most famous French novel, Flaubert's Madame Bovary. The excellent Italian writer Alberto Moravia also has many novels about this, the most famous being Il disprezzo and my favourite being Gli indifferenti. I also like D'Annunzio's Il piacere much more than The Great Gatsby. I would argue that variations of this theme are universal, with old writings like the Bibles's Qohelet and even more Sumer's Gilgamesh.

> Like wise, the American Dream is an American myth,

It's not a myth, it's just vastly overstated in its accessibility and chance of being able to achieve it.

I think what you said makes a lot of sense, and my earlier comment wasn’t very rigorous. More accurately, the most interesting thing about the United States is that it has almost stripped away all other influencing factors—no deep history, no influence from classical literature. If we set aside the atrocities committed against the Native Americans, it’s as if the country started from an untouched, resource-rich continent and rapidly evolved into the most advanced capitalist society. This makes the contrast between material wealth and the spiritual world especially stark and easy to observe.
