"Mrs Rinehart’s wealth is estimated at $35.6 billion, which represents a staggering gain of $1.1 billion per month since valuations for last year’s Rich List were ruled off in early September." (source AFR March 2021) At a projected gain of $1.1 billion/month, this would give her $50 billion by August 2022!
At present quarter of her wealth would be $8.9 billion or 8 months of projected earnings (and tax free)
Given her age of 67 with say a life expectancy of 20 years it is reasonable to assume that her wealth would be at least $150 billion by then. If her estate paid the US death tax rate of 40%, that would amount to $60 Billion so a $8.9 billion donation would be the better option, IMO.
A similar argument applies to the other 104 Billionaires, IMO.
