I have spent years trying to debunk this. The entrepreneurial spirit Nigerians have quickly falters when we immigrate (ofcourse entrepreneurship in Nigeria is a little different than we are used to, but I digress), except around things that service other fellow Nigerians/Africans (restaurants, lounges, African stores, immigration consultation, buying scrap cars and exporting etc - these businesses usually cannot serve the broader community at scale and usually get into the "bad belle" politics of the Nigerian community. We also usually don't formalize and structure them adequately for many reasons - story for another day). Indians, Arab, Chinese etc. move and almost immediately, with community and immigration support, look to start businesses that support the local community (Ukrainian refugees who fled the war in 2022 are already another example) but also with almost unified support from a well integrated immigrant community - who have established themselves in the banking and financial system, local politics, business leadership etc. Nigerians, on the other hand remain individualistic and compete with each other with the only semblance of unity being via religious institutions (and not broadly, like Nigerian Christians, more like "Redeem members") or maybe professional associations. The few who break this cycle don't see themselves as members of the broader Nigerian immigrant community with a responsibility to said community. This discussion needs to be had, I am very open to it.
