That logic is bad because while yes, it’s taxed at a lower rate, you can’t access it until you turn 67!!! If you access it before then you get slugged with a huge tax on it.
It’s like when I see people telling others who are struggling to put food on the table or petrol in the car to make sure they contribute to their own super to the max every year - it’s a stupid idea, yet many of the people who say things like that also think like you do in your post, which makes no sense.
Successful people are already punished enough by the tax man for being good at what they do. Finding more ways to fuck them over isn’t going to end well for our country and economy, as eventually they’ll all up and leave, taking 50% of the countries income tax with them.

No, taxing wealth and assets isn’t the answer. People shouldn’t be punished simply for being successful and owning things.
Your last point is - making corporations actually pay taxes. No more Apple Australia buying iPhones from Apple Scotland for the exact same price they sell them to customers for, meaning no profit in Australia, for example. No more mining giants paying nothing to literally sell the ground out from under us.
Income tax should be abolished, and instead make it spending/usage based. Spend more pay more.
The only thing I agree with “taxing the rich” for is fines - they should be percentage based. $1000 for your passenger having their seatbelt slightly off hurts someone earning $60k a lot more than it hurts someone earning $600k.
