Earlier quoted context omitted.
Vermont is 32nd in per capita GDP. Poorest would be Mississippi, dead last. California is indeed a massive economy and we're ranked 10th in per capita GDP. https://en.wikipedia.org/wiki/List_of_U.S._states_by_GDP_per... One point about our size. When CA does something at the state level a lot of other states follow along. Minnesota can't dictate to manufacturers but CA can.
That's GDP per capita. CA is the largest state in terms of overall GDP. Overall population/economy size matters, not just per-capita.
By comparison, Mississippi cannot afford this. They're basically supported by states like California; their economy is trivial and they're propped up by defense spending.
