When deciding what is fair in tax, we should perhaps consider not how much is paid in tax, but how much remains after tax. If a middle to low income earner pays $10k in tax, but then has trouble paying their bills, or keeping a roof over their head, have they paid a fair share? When a bilionaire pays $100m in taxes and has billions left to fritter away on going to space or playing with crypto stocks, have they paid a fair share?
