A national capital somewhere in the south would have been a heathy development for Argentina. Too much power is concentrated in Buenos Aires, to the detriment to the rest of the country. For one, the railroads would probably never have fallen into the recent state of disrepair. More German immigration to the south as well. On the whole, a more prosperous nation, the undisputed strongest country in South America. Amazing how much a little bit of infrastructure can change the fortunes of a country.
