For the record - I'm not saying it's IMPOSSIBLE for government to ever sell infrastructure off - just that it must be done right, with due cognisance that it's not their property. So that means  - before it can happen legitimately you need
1) A referendum, with a 2/3rds majority to pass - you can't sell the taxpayer's property unless the majority of the taxpayers agree. You need my consent to sell something which I own and which you are managing on my behalf.
2) The proceeds of the sale must be returned to the taxpayers. If it's a cash sale to an existing the company - then 100% of the proceeds must be paid out as a tax-refund to the taxpayers.If it's an existing entity becoming a private company (as with Telkom) then 100% of the SHARES of this company must be divided among the  taxpayers - much the way when Sanlam et. all. demutualized they had to give the shares to the existing policy holders under the old model - since those shares represented value from THEIR investments.
