South and Central America have bigger fish to fry than worrying about prudish neovictorian attitudes.
Maybe you should ask some of the indigenous peoples oh wait the colonizers pretty much wiped them out didn't they
North America remained available so late to colonization because the Spanish saw it as worthless as it didn't fit at all with their latifundial industry, precisely because it lacked the population and the farming that could easily be converted over to estates.
A significant part of North America is also Latin America, and vice-versa.

Therr were large populations of people virtually (and sometime precisely) enslaved by the Spabish as agrarian workforce; they weren’t always specifically agrarian (any more than any other preindustrial population, including the colonizers) before that.
And, yes, through enslavement and other mistreatment, they, and even moreso their pre-conquest identities and cultures, were often wiped out. Sure, there are some remnants and admixture with the colonizers and other imported subject populations; that’s true of the native subjects of genocide in the parts of North America colonized by the British and French, as well.
Latinx is a term invented and used by US cultural colonialists, that's both subjugating and xenophobic.
