so your math is slightly off. with 3 trillion in GDP ($USD3,000,000,000,000) with 300 million people (300,000,000people) yields around 10 thousand $/person ($USD3,000,0~~00,000,000~~/3~~00,000,000~~people or $USD~~3~~0,000/~~3~~ people or $USD10,000/person) in economic activity generated, assuming it is spread equally. my estimate is sizeable larger. pulling actual figures: in 2023 US GDP was $27.36 trillion and population 334.9 million. If we were to round to estimate, i'd say $USD30 trillion and 300 million people). that estimation makes the math more like $USD100,000/person ($USD250,000/household). Actual numbers math comes out around $USD81,700/person ($USD204,300/household). since the median household income is (last period we had both measures is 2023, hence the choice of the year) $USD83,730 and per capita personal income is $USD57,937 (average household size was 2.5 people, so a per capita personal income of 57,937 would either yield a household income of $USD144,842.50/household {going the other way, $USD83,730/household/(2.5people/household) = $USD33,492/person} or exclude a lot of people for "reasons" it's been way too long since i looked into economic demography i can only invent said reasons. but massive income inequality and theft could definitely skew things.)
