> In a culture where memorization and concrete thinking is used to compare $n people within that culture, creativity is inherently more risky
Yes, but the "culture where memorization.." is the culture of school. Says nothing about the culture of the larger society.
Here's a different way to look at it:
In a society where there is a lot of poverty, quite a bit of creativity is required to just get by. You can see this in poverty-stricken societies everywhere from rural China, India, Nigera, and poverty-stricken parts of the USA. Everything from crazy inventions/repairs to innovation in ways of living, getting some cash, stretching bills, toys and games, helping each other... Tontines and savings clubs have been re-invented all over the planet, yes, even in Brooklyn.
Whereas in parts of the US, on the other hand, many people have a lot of money to play with for quite a while and are perfectly happy to have others do their cooking, singing, storytelling, and manufacturing. To discard something malfunctioning and simply buy another.
The point is, people all over the world can afford to be less risk-taking (read: less creative) when they have more less to lose and can afford to throw assets at the problems.
