Hi news24
This is a tough position you're in, and I don't think anyone can really give you an objective answer. In the end you will have to decide what is best for you and your wife and child-to-be. However, here are some things you should think about (which may help you make a decision):
* Clearly you've already done some research and realise that the job market in SA is tough at the moment. As a female with an honours degree in mechanical engineering and 7 years experience, I thought it would be incredibly easy for me to find a job. In reality, it took me a year of job interviews and job hunting before I finally found something. So it's tough out here at the moment.
* What kind of lifestyle do you want to live? Both a life in the USA and a life in SA can have its upsides (and also downsides). Which one do you really want, and which one's inconveniences or hassles are you willing to tolerate? Remember - in SA we're starting to be affected more and more by things like power cuts, water cuts, random and unpredictable strikes by various service sectors (the post office is currently on strike, earlier in the week there was a threat for the Gautrain train drivers to strike, nevermind all the other strikes which I'm sure you've read about). On the flip side - our standard of living is still not too bad (most of the middle class, I think, can afford to have a domestic worker come in once a week).
* What kind of future would like your for child? And how do you want to raise your child? In SA your child can grow up knowing what it means to be a child of Africa and to really understand all the cultural influences that makes South Africans so different and unique. In the USA your child may grow up to be a materialistic, shallow brat. On the other hand, your child may be exposed to crime in SA at a very young age, while in the USA (I think) the state-funded standard of education isn't too bad.
In terms of your qualification and job prospects: I had a geologist friend who did exploration geology for mines. Ironically, most of the work she did was in the rest of Africa and not really in South Africa. Another geologist friend of mine is now at De Beers in Cape Town doing marine geology stuff (I don't know the details). There's also the Council for Geosciences, but I think that's mostly research-based work.
Offshore drilling and fracking? Here? Not so much. At least not in the short term.
I don't know if this is something you would consider, but have you thought about perhaps going back to University full-time to do a masters or PhD? There are bursaries out there for eligible candidates, and it may make it easy for you to transition back into the job market in SA if you start off as a student.
Anyway, good luck with this decision, but whichever one you choose, you will be happy (our brains are wired that way). The Freakonomics guys say you should just flip a coin when it comes to decisions like this, mainly because it's irrelevant which one you choose because you are wired to make the best out of the situation anyway. So...... if all else fails: flip a coin!
