Thanks, can you provide a source for that? Was that true for indiginous people in the Spanish colonies in the Americas in the 16th and 17th century already? Cause these people were not better off. Spain's colonial rule was as brutal and genocidal as any other. The common whitewashing myth goes that the indigenous population of South America 'was reduced' to large parts in this era due to not being immunologicaly prepared to the 'flu'. Well, they were not 'immunologically' prepared to the metal swords and armour and the bullets of the conquistadores. Many of those who survived were killed by working themselves to death in the forced labour system in notorious Spanish silver mines (see e.g. PotosΓ). Let's be careful not to portray Spanish colonialism as being something 'civilized'* by the omission of this, but maybe that wasn't your intention.
*Well maybe it was civilized, depending on your view on civilization.
It's low hanging because it's overweight.
