In the Americas — North, Meso and South — the first Europeans to arrive in the 15th and 16th centuries reported dense settlement and large-scale farming. Some of them were simply not believed. Spaniards such as the explorer Francisco de Orellana and the missionary Brother Gaspar de Carvajal, who travelled the length of the Amazon river in 1542, claimed that they had seen walled cities in which many thousands of people lived, raised highways and extensive farming along its banks. When later expeditions visited the river, they found no trace of them, just dense forest to the water’s edge and small scattered bands of hunter-gatherers. Orellana and Carvajal’s reports were dismissed as the ravings of fantasists, seeking to boost commercial interest in the lands they had explored.

It was not until the late 20th century that investigations by archaeologists such as Anna Roosevelt at the University of Illinois at Chicago and Michael Heckenberger at the University of Florida suggested that Orellana and Carvajal’s accounts were probably accurate.

Haha.

It is likely that these communities were established during the Ice Age, when the Amazon basin was largely savannah, and not tropical rain forest. So maybe they were doomed anyway.

My understanding is that Peronism is a kind of semi-socialist command economy, perhaps akin to Hitler’s National Socialism where the government allows the illusion of private ownership but owners are not allowed to make their own economic decisions.

One example I recall is that successful companies were able to provide various benefits to employees; Peron mandated that ALL companies provide these benefits. This drove many marginal companies out of business.

Anyway the point is that the old world exported a lot of bad ideas, such as Marxist socialism and state centralism, alongside the technological advances that came about before some of those bad ideas took root.
