Both of those points are spot on. The European underclass immigrated to Argentina just as they did to the US in big numbers before and after WW1. Many Italians came, and in the '30s they brought Mussolini's brand of Fascist Socialism with them. Peron adopted it and used rhetoric and give aways to hoodwink the lower class into keeping him in power. The template stands today.
