How do I know? Because my parents earning ~1000 USD per month each living in Poland have higher standard of living than most Americans. Despite paying ~30% taxes.
You have to add up what the taxes pay for in the calculation. Free healthcare, free university education, good public transport, low inequality (= low crime). All of that adds up to higher standard of living achievable with pretty shitty earnings.
Oh and before you blame it on military spending - we spend higher% of GDP on military than USA. Russia is a shitty neighbor, we have to.
American problems are exactly the opposite of what Americans think they are. You are in dire need of some social democracy.
