So basically half the world then

You just like that 'fact' cause ure a minority

Be it true or not
Im pretty confident just as many places where minorities do well in there are places where they do bad in. So I dont buy the "most cases" stat you brought up. Feels thumb sucked or cherry picked
PS. The Khoi-San say whaaaat
Not entirely true. Japanese Americans, Irish Americans, German Americans - outperforming.
In SA, Zimbabweans, Malawians, Afrikaners, English - outperforming the local populace. Even the average Venda South African is richer (although I'm sure Ramaposa scews the stats a bit)
Here is the article on the book. I have it on pdf if you really want to read it (only 139 pages). S
In Africa the Indians founded the textile industry and throughout the outperform the local populace.
The Catalonia is is no different.
In Scottland it is no different.
In Malaysia the Chinese minority (despite suffering affirmative action discrimination, owns most of the land).
In Sri Lanka, the tamils were better off
In Nigeria the ebus.
In Czechoslovakia the germans in the Sudetenland were more skilled on average than the rest of the country (the majority discriminated against them, and then was surprised when they liked the nazis!).
A well documented study of this was done by the Hoover institute by the American economist Thomas sowell. I suggest that you read his book called ''intellectuals and race''.
