Prince understands the issues and is being very dishonest by proposing colonization as a solution to bad governance problems.
I truly believe that if you let citizens from X African country truly elect their leaders unencumbered or have at the head of the country someone who they truly voted for then these problems fix themselves. The problems stem from crisis of legitimacy for a lot of countries. When the person who is governing you is illegitimate, then he/she is not accountable to you in socially, economically and security/military. The Western powers know this however do not use their influence and power to actually force the will of many citizens from African countries to be reflected in their elected leaders.
All they do is denounce shambolic/opaque/fraudulent electoral processes to later accept it and then non-educated ppl talk about Africans as not deserving of democracy and how democracy is not intrinsically African or why do Africans keep electing leaders who are incompetent. It presents Africans as somehow complicit in their own suffering therefore requiring outside intervention (i.e. colonizers). The thing is a lot of African leaders are ILLEGITIMATE meaning they were not democratically elected and were SELECTED therefore the solution is the problem of internal legitimacy and not the perpetual myth of the innate inability of Africans properly governing themselves therefore requiring foreign interventions to fix their problems.
The best solution for the continent is actually the opposite of Prince's viewpoint, leave Africans alone because they are human beings like everyone else in this world capable of discerning what good and bad leadership looks like and elect those who will look out for their best interests.
