Mexico annexed after 1848

[Colin]

Mexico had only 1/3 of the US's population in 1848. Sure its 19th century rate of population growth woudl be larger than our timeline but you forget that mexico would be in a first world nation so it wouldn't grow as much as it did in our 21st century(instead of 110 million mexicans plus 20 million more in the US making 130 mexicans we'd see abotu 1/2 of that). We'd have about 70 million mexican-americans in that timeline. Thanks to air conditioning/demand for labor we'd see mexicans move north like how the blacks did so only about 30-40 million mexicans in the mexican states

If you already know all the answers Straha why the hell did you ask us for our own opinions?

That's quite interesting what you mentioned ag that the annexation of more area in Northern Mexico could have lead to a major shift to a southern power base. So the US becomes Brazil-like with the South like poor Northern Brazil and New England and the Midwest like richer Southern Brazil. What would we have in that inventuality? An Argentine superpower as Argentina gains a large number of the immigrants that would have gone to the United States? That to me sounds incredibly interesting. Of course Argentina would have to keep its internal political order to accomplish remaining a first world nation.

All Argentina needed to remain a first world nation was to have anyone but peron in power.

Well their decline began in the twenties with the socialist reforms of the Radicals and then got pregressively worse until Peron screwed things over royally.
