BBC reports on the mission of the Global Elders to help Zimbabwe. As usual, when one sees a pompous name - Global Elders - one should skeptically expect much form with little content. To begin with, the Elders could not even get into Zimbabwe - Robert Mugabe's ZANU-PF party thumbed their nose at the celebrity cast of this reality show. Furthermore, at 0:22 in the linked video: " The Elders wanted to know what had forced them to leave, and how they are surviving." Well, you have to be seen as doing something even if you can and will do nothing - as the bunch of washed up bureaucrats and politicians knows. So they are asking questions, the answers to which are available to anyone curious.
Where do you even begin to answer such an idiotic question? The poor souls in the Johannesburg church have run away from a place that:
1) Has cholera - a disease, which takes only clean water and sanitary sewer systems to eradicate. The government has abandoned all pretence to care for public health.
2) Is run by a gang of thugs who may lack the sophistication of Nazis in WW2 Germany, but make up for it with diligence, all the while employing their tested methods . The government not only does not protect people, it actively terrorizes anyone it even suspects might potentially be against it.
3) Has unemployment (data is highly suspect, but estimates range) between 80% and 90%. For all practical purposes, Zimbabwe has no economy. The only "productive" activities left are foraging for food, crime, and smuggling - mostly of people out of the country.
4) Has had white farmers (who happened to know how to actually grow food) expropriated, and any foreign or white-owned business forced to cede 51% equity interest. For all practical purposes, property rights do not exist in Zimbabwe.
5) Has inflation that not only has handily beaten any record human history knows, but is, by admission of the Zimbabwean Central Statistical Office, impossible to measure, because there are not enough goods in stores to do so. That admission came a year ago; since then, there have been rumors that these days the computers they use cannot handle the number of digits required to attempt to calculate inflation. A proxy for the Zimbabwean dollar based on shares of Old Mutual listed in Harare and London gives approximately 12 quadrillion Z$ for one US$. According to some estimates, inflation rate runs at 80 sextillion (10^21) per cent. For all practical purposes, Zimbabwe has no currency anymore.
6) Has widespread starvation (too many links to choose from). A story from a couple of years ago, which I cannot find a link to, claimed that in 2005 (to the best of my recollection), starvation was somewhat alleviated by an unusually generous "harvest" of caterpillars.
Usually, this is very near the end of the road for a dictator. To stay in power, a dictator needs an oppressive apparatus, usually a mix of army, police, and followers/allies. However, the army and police need to be paid, and followers/allies need favors. Such a situation can be very stable, as long as the economy produces enough for the dictator to pay. When collecting taxes does not do it, and there is no one with wealth left to steal from, you crank up the printing presses - inflation being a very regressive tax, which is also highly efficient in extracting distributed wealth from the poorest. But a point comes, when you cannot make people use your money - not even facing down the barrel of a gun, since you no longer have the guns. The army and police must be paid, and enough not only for their own physical survival, but for that of their immediate family, and likewise for other allies. When no matter how many zeroes you put on a currency bill, noone will give you a dollar or a loaf of bread for it, you - the dictator - have a serious problem. You try to clamp down on any speculation in hard currency (done a long time ago in Zimbabwe), and you try to deflect the pressure outward - evil colonial powers, subversive elements, etc. (also done long ago). Soon enough, you either have to start a war, or to plan to flee with whatever is left in the coffers or offshore bank accounts.
This is what some of the Elders most likely know (Annan, Tutu, Cardoso (Ph.D. in sociology), Brahimi) and some most likely do not (Machel, Bhatt), but ought to. What they do not want the unwashed masses to realize and clamor about is that we have on our hands a prime example of a case where many of their theories have fallen apart in a most spectacular manner. National sovereignty, non-intervention, disarming of populaces, humanitarian aid, wealth and income redistribution - all have failed Zimbabwe. The most humane thing to do for the Zimbabwean people at this point would be to airdrop a few thousand high-quality sniper rifles with instructions on how to use them and a mechanism to render the weapon useless after a couple of months. If Mugabe does not receive significant boost to his lead intake within that time frame - repeat. When he does - then, and only then, send in humanitarian aid.
