Democratically elected Emmerson Mnangagwa??? The guy gained power via a coup and rigged the July 2018 elections! The economy is just negatively reacting to his election fraud, simple!
If this was true, what was Zimbabweans too looking till such a terrible leader took over power, and things like coup like this is very difficult to get the person to step down, except maybe they use force on him, the way it happened to Gadhafi.
If I was the president, I would just stepped down for another president, hoping that the new president will be able to handle the bad situation of thins, and when handling to any president, they need to look for president that have real use, I mean one that is a technocrat and would be able to proffer solution in a professional way to the country and to its citizens.
I am not sure orienting of more money would be the answer to their problem, they just need to change the leader, once they change the leader, that is all.
