Quote #1
"What do I want to see them for? What, am I in trouble?"
Americans have a deep-seated mistrust of their government, as Indy evinces here. The film also makes it clear that Indy is a mercenary working for the government: He's not an official agent. That in and of itself seems to reflect the high value Americans place on individualism, which ironically makes Indy more "American" than the army guys who hire him.
Quote #2
"It is as if the Pharaohs have returned!"
We get a little Third World commentary here: acknowledging the exploitation of the local natives by a European power that couldn't give two figs for their welfare. We don't know what the accident rate is on that dig, but we're betting the Egyptians get it much worse than the Germans.
Quote #3
"They have not one brain among them! Except one, he's very clever. He's a … French archaeologist."
Sallah draws a quiet distinction here by mentioning that the only smart guy is French, and by default, that the Germans are uniformly stupid. It separates the villains along national lines, suggesting that Belloq might not be as bad as the company he keeps.
