I honestly cannot fathom people who revere billionaires, especially those known to be thugs and whose wealth was inherited. But as I said before, a matter for personal opinion.
However, as to whether or not he was such a brilliant businessman ... see this from his Wikipedia entry:
"If $100 million had been invested in the Australian sharemarket in September 1974 through a balanced portfolio of the top 200 companies, that portfolio would be worth a lot more than $6.9 billion in December 2005, possibly as much as $11 billion."
I take and agree with your point SERB .. but if we are quoting Wikipedia entries as fact .. we are all doomed ..
Also even limited consideration to that statement would lead me to question the validity of it .. does it allow for funds coming out each year for living costs, family dispersements, donations to charities, hospitals, Art galleries, tax, capital gain tax etc ... or is it just a simplified calculation of share value start and finish. ... I am certain if he didn't enjoy a punt and the dolce vita he would also have had a lot more than the 6.9 ..
