It is truly naive to think you can simply explain the higher crime rates and other problems simply by some black "culture" being inferior.
First of all,
there is no universal black culture. That fact alone makes your argument invalid. Black people just like any other group, have different cultures. Just the same way there's no single white culture. When you begin to say cultures are inferior, and at the same time falsely claim cultures can accurately be substituted with race in your language, your language borders racism and this is why your previous thread was removed after your last reply.
Secondly, your comparisons are nonsensical, because black people everywhere on the planet live under completely different conditions than other groups. In western countries, prejudice and discrimination makes it harder for them to get jobs and leads to marginalization, which we know causes higher crime rates. To say it is simply their culture
is not at all scientific. It is to make up a quick explanation for some data you have, just don't go on to say you have any evidence for it.
Another factor is that they've historically been in poverty in e.g. USA - they started out as slaves, ironically brougt to the country by people with the same kind of mindset who now think they are a problem - people who view them as inferior. Sadly statistics show that the American "dream" and other such ideas are nothing else than a few anecdotes, on top of the statistical fact that the majority of the population ends up in the same social stratum they were born in. This is true
regardless of race or culture.
Now for comparing Africa to Europe etc., these areas each have different resources, different climates, many forested areas in Africa simply do not have soil that makes them fit for building infrastructure for example. But we certainly have seen examples of civilizations - e.g. Egypt could be mentioned, which built the pyramids, discovered mathematical relations long before Europe and utilized the periodic flooding of the Nile to grow crops.
Also, oppression isn't an excuse in this case. Just think of Germany. They lost a goddamn World War. A few years later they got back in shape and did another World War. They lost it again. They lost two goddamn world wars in less than 50 years (not sure if it's exactly 50), but still, they managed to be one of the most developed nations on Earth. This has to be explained. Let's be honest now, do you think that if we replaced all the Germans and put Africans there, do you really think Germany would be a rich country? Come on
In WW1 Germany's losses were essentially 0 in terms of infrastructure, their losses were soldiers (which the allies felt roughly equally), weaponry (which became more or less replaced with more modern ones between the wars anyway), and of course an enormous amount of money they had to pay, which they couldn't. - They implemented roughly Keynesian economic policies which ended the market's never-ending spiral but at the same time made their debt inflate... a problem they could ignore until WW2 and bigger problems stole people's attention.
The fact that their economic problems had 0 to do with infrastructure, and everything to do with essentially the market and money system breaking down, is a very important difference that makes it a bad comparison to Africa. Europe had taken over and managed Africa's infrastructure. They had developed it only to suit their
own needs - so the arbitrary countries they left behind were focused on a few extremely narrow economic areas that European countries needed. And in most cases the exploitation has simply continued unofficially, now just by western corporations rather than states. So many former colonies are locked in a position where their economy relies on a very unstable international market and can't satisfy their own needs. Unlike Germany whose infrastructure wasn't built only to serve some other country's needs.
As for whether replacing Germans with Africans would change anything... To answer that you need to explain what it even implies. For every German, you substitute with an African, with the same education as before, the same job as before, and all other relations being the same... I see no reason why it would be different.
Unless you don't mean to substitute the educations and other things - in which case your comparison is flawed.
Or, unless you think you can make the substitution of people without their ideas. In that case I don't see why you'd speak of cultures being inferior when you evidently mean people and not their ideas.
Tl;dr: I think black people should be treated equally to all other humans. They should all be judged individually and not because they're black. The crime and other problems mentioned will only get worse if we think it is acceptable to consider people inferior because of their biology. If we instead meet people without prejudice, get rid of inheritance and other artifacts of our broken economic system that locks generations into social strata, then the problems can be solved.
Edit: Merged back into the old black people thread excluding some of the latest posts. But please make sure not to break the no racism rules in the future.
