I'm currently in Africa, a continent full of dictators whose presumably noble original intentions have morphed into despotism as those in charge of a country conflate their personal best interests, with the country's overall interest.
Even nominally democratic South Africa resembles a one party state (in the Singapore tradition, rather than the more malign alternatives) with the ANC undefeatable in the national parliament and eight of the nine provincial governments.
The best of intentions often descend into a mixture of incompetence and even corruption when a political party, or a politician, rules for too long with no real chance of losing an election to the opposition.
In South Africa, one of the nine provincial governments has elected a Premier from a different party. In Western Cape, Helen Zille is the Governor, representing the Democratic Alliance which she is also the federal leader of.
Zille is praised widely in Cape Town, a city she used to be the Mayor of, and was proclaimed World's best Mayor in 2008. In Cape Town crime has declined massively (down 90% in the BCD over five years) and the economy grew 12% in her first two years in office.
