> In 2023, California's gross domestic product (GDP) was about $3.9 trillion, comprising 14% of national GDP ($27.7 trillion). Texas and New York are the next largest state economies, at 9% and 8%, respectively.[1]

CA is a huge economy but by no means is the US just CA + 49 other states. Might be fairer to say it’s CA+NY+TX+FL but at that point you’re just aggregating the population.
