Forget about fast food and look at it this way:
SA has a trade surplus. ie...Exports exceed our imports. So foreigners are buying SA products more than what we are buying from them.
This is good for the ZAR as they are buying ZAR via products. The ZAR will keep strengthening as long as we have a trade surplus. The revival of the commodity sector (SA is commodity driven) is the main driving force of the ZAR increasing in value.
Negative local political news will drive the ZAR down but as long as we have a trade surplus it will eventually regain lost ground depending on the severity of the news.
This can get complicated when comparing to currencies other than the USD.
That I understand, but I feel that is a flawed economy, because... Correct me if I am wrong, but does this not basically mean we export our raw materials for next to nothing and then we buy back the expensive refined and processed products?! Thus we will never make money as exporting to buy back the end product will always be more expensive.
Should government not start creating companies that can use our raw resources to manufacture products we can sell to other countries instead of other countries buying our raw resources for bottom price and then they manufacture products and we end up paying 10 times more to buy those products which we could've manufacture our self?
