Is it really far cheaper to live here than in other countries? I mean we get taxed a lot, have to pay for our own security, medical aid, more expensive transportation (no decent public transport and very expensive cars) and so forth.
Private Medical cover is becoming more common in lots of most places (e.g. in my 8 years working as a professional in London, there was not one job where "BUPA" wasn't a Benefit). Medical aid is not
really expensive in SA, unlike USA (albeit may or may not be included in "salary" figures)
Security - yes that is a quite uniquely South African expense, but come on, how much do you pay for ADT - less than 5,000/yr surely? (Ours is like 300/mo?)
Tax - structuring is important no matter the country, try not to be an employee!
Cars are not more expensive here really. A new car costs more yes, a used ca costs more, yes... But you see the real COST of owning a car is the difference between those two. In the UK once a car is 10 years old its almost worthless, in SA a Polo just doesnt depreciate at all!
What's cheaper in SA - home help, cleaners, eating out, booze... Sunshine. Clear star filled nights (due to load shedding

)... Getting away with crimes... Life... So yes things are cheaper in SA too
Editted as was quite unreadable first time!
