National socialism is coporatist in nature, countries with a reasonably similiar economic model are the scandanavian societies,
Why do you care so much about ethnicity and race? You do know racialism officially been considered effectively peuso science since the mid 20th century, the closest modern link to impy serious differences between various groups would be IQ. That can be explained by a number of factors including things that suppress IQ , such as malnutrition (which severely impacts cognitive abilities, and also your iq), especially during formative years,
Given this (and yes if you ask for a citation i can provide it on the malnutrition info) then we could expect to see a direct corilation between say calorie count and malnutrition, with a few exceptions where its possible to be both (such as the usa)
In the western world where food calories are high, you find higher average iqs, diets are also much more varied and much more likely to satiate all your needs, such as vitamin requirements etc. This being conducive to healthy human growth including that of the brain
Malnurishment map, this being critical because to stay alive your body sacrifices alot,
Combine this with the fact that poorer nations tend to have mono diets, ie eating the same food every day, chicken and rice being common mono diets in many countries, which will keep you alive but will not serve your other needs in your body like plenty of fruit or veg does.
African Americans also fall into this pattern, they tend to also be more likely to suffer malnutrition, however this is more tied to very poor education than poverty on its own, although that contributes substantially still because cheaper foods tends to be far less healthy.
Now this isnt even scratching the whole host of other disadvantages and problems that many poor people, including africans but also many other nations face.
For example a key contributor (aside from collapse of culture) in african families in the usa being stable is the drug war, profitable to lock people up etc etc.
