Of course, he spoke fluent English and told me how his parents had paid for an English teacher for him.

AFAIK this is a major tell in Venezuela because bourgeois and petite-bourgeois will talk to each other in English they learned from private sources. They frequently travel to the US, Canada, Australia, etc. as tourists or to invest in rentals. It becomes incredibly suspect when you meet a Venezuelan and their English is really good.

They are likely not from the working class or poor,

Pretty much. I knew this one Venezuelan guy who was always comparing democrats to communists. When you hear him talk about what his family did back in Venezuela, he'd talk about their properties in Miami getting them in trouble with the government so they "had to flee the country." Dude was suspiciously pale and to no one's surprise, was also homophobic, classist, sexist, and colorist.
