We have too much to lose, BUT I did a few sums and worked out that based on the cost of living exceeding our yearly increases/income, we will reach a point in the near future where the cost of living in SA will be so high, that you won't have money left to pay your house installment.It is simple maths - cost of living increases by 20%, salary increase by 5%, Tax and interest rate increase by x% - bang, goodbye house and car. Then we have nothing to lose. You can actually do this very precisely in a spreadsheet.
The cost of living in SA is already so high (not money) that we have nothing to lose.
