A pity we can't on your math though.
60% return taken out each year & that 600k is put in the bank at a measly 5% p.a. you are still $6M better off than your 10% compounding over 50 years.
Obviously you could get a 10% return on every $600k taken out over 50 years and be multiples better off.
Hey but that's just how the real world works.
People don't just receive dividends and put it under the mattress.
Anyway this has been yet another exercise in futility.
Adios.
