Knowledge was shared much more in Alterra, because people knew it would be good for the territory. This was still something the Golds hadn't completely comprehended but had seen in many forms.
Not even counting Oslo's upgrade, they had witnessed stores selling specific spices that demoed several recipes for free.
While they found out it was a 'great marketing' strategy (Otto learned a lot) to sell the product, most aborigines normally wouldn't be willing to share recipes just by instinct.
They had also learned a lot about apprenticeships and the like, and they knew it wasn't anything like the apprenticeships that they knew. An apprentice here would learn years ahead of his peers under another master!
They had also read the so-called newspaper (Oslo brought one home) to show that a school would be opening for an affordable price.
