I think the earnings model is good. If you earned it, it goes on your income statement. That being said Aussie income tax for me is significantly high 😞 ah well what can I do.
Americans have a fat lower CGT which is amazing something like 7% someone was saying. Where as in Australia it's 50% but can come down to 25% if you've held for over 12 months.
The individual tax in US is actually higher than most places, but they get less benefit for it - "greatest country on earth" :D
