Tax Reforms Suggestion/ Limitarianism

Tax reforms according to the new political current/movement Limitarianism that aims to provide access for all to current prosperity.

For Example ( numbers to be changed after study)
Income Tax : provide everyone with an unconditional global basic income and don’t charge tax up until average income. Above that a progressive increase with an upper limit of 1 Million from where 100% is paid to discourage to get more market.
Inheritance Tax : no tax untill 0,5 Million, then progressive tax up to 100% from 10 Million
Wealth Tax :  no tax till 100.000 euro and then a progressive tax up to 100% above 1 billion. No dangerous, selfish billionaires anymore.
