I've always been in favour of tiered consumption taxes. Basic neccessities of life aren't taxed. Sorta nice stuff gets taxed a bit. Uber lux stuff and harmful stuff gets taxed all the fucking way. Example: bus pass? Free. Subcompact cheap EV? 20% tax. Lambo? 300% tax. Rich fuckers have way too many ways of getting out of paying income tax. Tax the stuff instead so that you can't live like a rich person without paying the kind of taxes rich people should be paying.
