Isn't this economy going downhill just like Zimbabwe economy did under Charles Mugabe?

There has never been a successful black leader in history so what you going to say Joseph Mandele the people even the blacks were so happy to get rid of him they celebrated he almost starved that country to death. So whos next don't say Anwar Sadat cause he was Egyptian. So who's next your down to Papa Doc, Idi Amin, etc. What a resume these black leaders have.
