To answer why coming to the UK (in no particular order):
1) I have always been a true loyal Brit and have always wanted to come back to the UK
2) To escape the reverse apartheid as I have now reached the glass ceiling here.
3) Anywhere you go, there is crime, A crime in the UK makes headlines, a crime in SA might make the sports section if it's gruesome enough. To give an example, my house has the following security features: Laser beams, Electric Fencing, Pallisades, burglar bars on all windows, Trellidors on all the doors, alarm system coupled to a security company. All that and they'll still be able to get in.
4) The next President will send the country down the same path as Zimbabwe.
5) Being analytically minded, I have assessed to "cost of living". Sure, petrol is far more expensive, cars, houses etc but on an average, taking everything into account, it's only 1.4 times more expensive in the UK. Take for example, a house loan of 150,000 pounds at an interest of 7% compare that to a house loan here of 1,500,000 at 15%, You spend your life paying off interest as the rate is higher and the amount is higher.
