Just copying Argentina:
“In the 43 years leading up to 1914, GDP had grown at an annual rate of 6%, the fastest recorded in the world. The country was a magnet for European immigrants, who flocked to find work on the fertile pampas, where crops and cattle were propelling Argentinas expansion. In 1914 half of Buenos Airess population was foreign-born.”
“The country ranked among the ten richest in the world, after the likes of Australia, Britain and the United States, but ahead of France, Germany and Italy. Its income per head was 92% of the average of 16 rich economies. From this vantage point, it looked down its nose at its neighbours: Brazils population was less than a quarter as well-off.”
Then came Mussolini in Italy, and the Argies said, "I'd like some of that!"
