How is Argentine success explained?

After the May Revolution in 1810 and independence in 1816, Argentina had difficulty finding a model for prosperity. After the governments of Juan Manuel de Rosas, and his overthrow in the Battle of Caseros (1852), the country embarked on the Constitutional project of Juan Bautista Alberdi (1853/60), of clear liberal orientation. The new political and legal framework was pro-immigration, defended free enterprise, kept the state separate out of free enterprise, and limited itself to offering the appropriate legal framework within the rule of law. The results in terms of attracting immigrants, growth, economic development, are so statistically clear, that they need no explanation. The relationship between the policies applied and the results are as evident as the opposite case current Venezuela.
