Why Western-style democracy is not suitable for Africa

George Ayittey suggests that we evolve a form democracy more in line with our heritage:

...let each group choose their leaders and place them in a National Assembly. Next, let each province or state choose their leaders and place them in a National Council.Choose the president from this National Council and avoid the huge expenditures on election campaigning that comes with Western-style democracy. Those resources can be better put to development in poor African countries...Next, let the president and National Council take their decisions by consensus. If there is a deadlock, refer the issue to the National Assembly. This type of democracy is in consonance with our own African heritage.
