I'm interested to know your view as to, what stage of the sequence does the discrimination happen? and who is doing the discriminating?
is this happening at the hiring stage? ie African Americans get to the job interview but never get hired?
or they never get to the interview, in fact, they didn't pursue this career option at all for economic reasons? maybe couldnt access the colleges?
presumably those people are black, so...why did they make it and natives didnt?
this would suggest that if prejudice exists in the system that its not about the skin color per se. that there is something else at play , right?
Again, you are seeking simple answers to difficult questions.
Let me give you a stat that has been proven a few times. Given two identical resumes, a black sounding name doesn't get selected for interview. In USA certain names are associated more with Africa-Americans. So that is implicit bias at work right there. You can look up the studies and research on that aspect.
A bigger problem are the obstacles in the opportunities for attending better schools and colleges. It is due to combination of historical discrimination, the policies that disadvantaged those with less income, systemic discrimination faced by African-Americans today based on where they live (inner cities), income levels (class), prejudiced built into the process for determining eligibility (e.g. housing loans), and myriad other small and big things.
From there then is a cultural problem within the African American community of not prizing the education. Which is a chicken and egg situation. There is a lack of access to good education and that lack of access then justifies lack of interest in education. It is becoming very hard for most Americans to access education beyond high school. For people who are coming for middle class or less it is becoming very hard to pay for the college tuition fees. For the African Americans as a group this is double whammy because as a percentage a lot of them are poor (and they are poor due to the history of what happened to them - they were never given a chance to build what is called generational wealth for last 200 years which is approximately 8 to 10 generations). On top of it when you factor in systemic bias, prejudice and discrimination it becomes a triple whammy. So the decks are stacked very high for someone coming from that background to succeed. The kids instead want to become next rap artist or the next sportsperson i.e. professional athletes. However there are so few opportunities to become either because that is very competitive. It is like every kid in the country wanting to be an Olympic athlete or a movie star. For every movie star and professional athlete there are 100 or 1000 decent paying jobs for a college graduate. In high paying fields like engineering, law, finance, healthcare you can live an upper middle class lifestyle. For some then it is boom or bust. At highschool, or college level you soon find out you are not cut for reaching the tip of the pyramid (professional athlete or musician that earns in millions). A bust without fallback means you are not able to improve your station in life.
Now add to that a volatile mix of higher crime rates, disproportionately higher incarcerations rates (during most productive years of life), lack of opportunities for upward mobility, poor social safety net. Then as an African American born and living in the inner city or poorer neighborhoids you are being asked to take the stairs while others get to take escalators or elevators (lifts).
The African immigrants who migrate to US don't have any of the above baggage. They are already self-selected in that they were able to beat their own challenges back home and move abroad for higher studies. Most African immigrants or expatriates I met in USA and Europe are usually highly educated or professional. Like any immigrant groups there are those who are in disadvantaged sections of the society. But they too don't have the baggage that the African-Americans do. Yes they too face discrimination due to skin color, but it isn't a lifetime of discrimination till they reached the American shores.
Many African-American leaders who have reached leadership position have their own stories to tell about something happening to them because of their skin color. Every single of them. I haven't yet heard from a single African-American who reached a leadership position claim they never experienced being judged because of their skin color.
Everything I wrote is simplified narrative and glossing over many complexities and nuances. There can be a counter argument for each point I mentioned. That is like looking at an individual tree and loosing the sight of the forest.
P.S. - I read
@dav7802 's post after posting mine. It is two post above this and shows 25 different statistics. If you read those first, you will get many of the things I have claimed in the this post.
