Without a functioning economy delivery of social services depends on foreign assistance, neither sustainable nor healthy. Of course a functioning economy requires investment, which won't happen without some level of political stability, and around we go in circles. Call it the African shuffle; very difficult to find a practical intervention point.

Depends on what you call a functioning economy.
DRC never stopped to be an investing place and was much more profitable for investor when was at war.
In Liberia, the direct effect of the raw material crises in the 70 led to the total disruption of a functioning economy that led to a first revolution and the arrival of Samuel Doe in power. The fact that he did not even try to restore the social services favorise the military adventure of Charles Taylor who entered in the country without local insurgent network but 200 mercenaries (mainly Liberian).
In Zimbabwe, as the economy was completely dysfunctional, social services were still functioning and the country was stable despite having a war affected economy.

Economy is not the solution to initiate stability and create conditions for investment. Stability is. Only social services equally shared can provide such stability. Once you have fund the stability, then you are in much better position to bargain your investments in the country… But may be it is too social/populace/people oriented?

JMA:
As you pointed it, the problem is one man one vote, ONCE.
While it should be one man, one vote: several times.
