Whilst it is true that Crime is everywhere (hence the need for police services everywhere), the critical difference between SA and say any "Developed World" country is that over there, there is a palpable difference between those called "The Criminals" and those called "The Police".

Over here in sunny SA, you'd be hard pressed (and mugged and shot at and and and) to tell the difference most times between the Criminals and the Cops. Witness the frequency with which we replace our police commissioners not because they're in the line of fire but since they're in the line for back-pocket packets. Of Money!

Another factor is: Social Services and of course "Serving the Public Trust".
We in SA know so little of what these are that most reading this will have to Google it to find out exactly what these terms mean. And once one has seen the benefits of living in a co-operative, civilised society that has these characteristics, it's hard to justify living in the opposite which is a hostile, barbaric society like South Africa.

Ask yourself a very simple question: If your car were to break down, would a random stranger stop and try and help? Would you stop to help a random stranger stranded by the side of the road?
No. We fear all sorts of things and trust no other member of the public. With anything.

And this costs heaps in money, tension, stress and so forth if you cannot rely on the "Public Trust" for anything.

And this is why people emigrate. Why pay so much tax when all that happens is it's either thrown back into your face with some racial insult and threats or thrown down the black hole. The very very black hole.
