The corruption feeds off of the US, Asian, and European funds (it's a naked neoliberalism/neocoloniasm because greed among the elite in the 54 doesn't result in the American level of suburban wealth).
Many people on the ground have a plan, but you're fighting so many battles that Trump is the least of your concern tbh. You can remove Trump but the US empire will still fight against your right to self-determination. It's not like Trump has this vastly "different" concept of America's relationship with Africa than his predecessors.
It also doesn't help that every time a country begins making positive gains they get hit by devastating environmental and public health disasters.
