A simple google search regarding "white ownership on JSE" will confirm that the percentage is arround 40-45%. For example Mike Schussler's comment below:
Black South Africans own 23% worth of the listed shares on the JSE. White SA shareholding represents 45%, with foreigners (31%) and the state (1%) owning the rest.
The holdings of black South Africans – all African, coloured and Indian residents according to the department of trade and industry (dti) - in JSE companies have grown significantly over the past decade.
This trend will continue to accelerate as transformation in the workplace gains continues and more blacks contribute to retirement and other management funds.
These are the key findings from research into the demographics of shareholders in listed companies commissioned by Sake24 and conducted by Mike Schüssler, head of independent economists group economists.co.za.
My personal experience regarding employment of young, recently qualified "whites" stem from children from my circle of family, extended family, friends and ex-colleagues( who became good friends ) in SA. They range in age from 23 to 31years. I stopped counting when I reached 43 (there are more). All of these young people are tertiary and professionally qualified. They did not struggle to find employment and 90% plus are employed by companies, firms, universities , schools, etc. Only a handful are self employed - medical doctors/specialist and a chartered accountant and civil engineer.
Obviously this cannot be applicable to all spheres and levels of the community. What is clear is that the " no chance of employment/future for young white males " is not nearly an absolute.
There is a lot of merit in 2Gatjakkals post ( even more so in view of the recent earthquake and its effect on the already fragile NZ economy ) and his stats are not as "unreliable" as being made out to be.
The irony is that we have lost more NZ South African friends that left NZ for the same reason you want to leave SA( i.e. no future/employment for them or their children ) than who emigrated from SA.
