It's too bad that Brazil and Argentina can't get their act together because they have potential as destinations, but they continue to elect absolute clowns who eff up the economy. The inflation there makes investment a non-starter.
Macroeconomists often joke there are only four types of economies in the world --
Developed countries (e.g., U.S., Canada, western Europe, etc.)
Developing economies (most everybody else)
Japan
Argentina
Japan has no obvious reason to be prosperous based on its geography and natural resources. It is a small island nation with very little arable farmland (though good access to sea-based foods), very little in terms of mineral resources, and even less in terms of domestic fossil fuel resources. Japan is essentially just the rugged peaks of an underwater mountain range in an isolated corner of the Pacific Ocean.
Yet they thrive -- third-largest GDP after the U.S. and China, industrial powerhouse and a leader in countless industries, exports all over the world, influential culture, stable/successful politics.
Argentina has every reason to be successful -- close access to the Atlantic economy connecting eastern North America and western Europe, some of the best farmland in the world, the benefit of being in the southern hemisphere so its harvests always come during peak price conditions, incredible natural resources, mild temperature throughout most of its territory, really has everything that you need.
Yet it is a total basket case and has been for almost a century.
Policy and governance matters.
