The apartheid government may have been morally reprehensible, but at least it knew how to run a country. Either option is kind of shitty…
So, by the standard you imply with your comparison, the apartheid government—even more certainly than the present regime—did not know how to run a country.
That's fine, but that's also completely orthogonal to the point, which is that:
1/ By most standards, the effectiveness of government has plummetted since the end of apartheid. Crime is up; corruption has increased; resources are running out (nation-wide electricity blackouts last decade, now water); etc.
2/ Open government-sponsored racism still exists today, but most of it is considered to be commendable under the banner of affirmative action.
If we were to take race entirely out of the picture, the apartheid regime would be considered far more effective than the ANC regime. That, of course, is neither realistic nor fair… But we should aspire to a post-racial world where we race is no longer relevant, where both apartheid and affirmative action are considered revolting abominations, but also where we judge governments based on their net effectiveness.
My point is that comparing government effectiveness is not as easy as looking at results. This was exemplified by many of the communist satellite states to the USSR, which it sponsored for political gain to its own economic detriment. The satellite states flourished under communism, and as soon as the regime collapsed they suffered - was it the newly-elected democratic government's fault that industry had collapsed and there was rampant inflation, or was it just a long-term effect of previous government policy?
The government had an initial plan to redirect overcapacity in many areas (not just electricity) to rolling out services to those neglected by the Apartheid govt, and then after that to start building infrastructure again (not sure of specifics, maybe 5 years on?). The problem is that in most cases, this never happened. Hence the limits of most infrastructure are gradually being hit, with a knock-on effect for the economy.
Hear, hear. While "the better angels of our nature" should inform our aspirations, the political, social and economic facts-on-the-ground should inform what action should be taken in order to bring us closer to the ideal.
Affirmative-action is a symptomatic treatment (that could be argued as being punitive) which achieves little-to-nothing in solving the root-problem, while creating a whole new set of problems. Successful integration of former-colonial and indigenous peoples in ZA would have been an unprecedented achievement, but adopting policies that are so obviously regressive will not bring that into reality.
