First of all, Why would he?!
Even if you are educated or a professional by Western standards, their technology far surpasses our own, so what benefit to society would you be in? You would have go into years of training to learn and fix the technology their. To be a fit member of society. Free educations for 100,000s of Black people?! Come on son. The tax increase though
You think Boonquiesha and Darquarious would be productive members of society their? They ain't shyt here, what makes you think they will be shyt their? Welfare leeches and bummy, dusty males?! You think TChalla would let those clowns in? Wakandans would be highly offended of swarms of unproductive members of black society relocate to Wakanda and don't do shyt their. Just sucking up all the resources. Won't even bother to learn the language. Being disrespectful to the natives. Wakanda is small for a reason. It's like Monacco. Small rich country. If Monacoo opened her borders in Europe then that counrty would be bankrupted in a heartbeat.
The biggest problem as I said before is black professionals being useless over their because high technology required little maintenance thus a lot of technical/medical skills in our world would be useless over their.
