Again with people of limited knowledge and intellectual assuming GDP means anything relevant to the point they're making, but it doesn't.
Exhibit A, almost 9% of GDP is tourism. Not only is that not productive in any sense of the word, that will crater thanks to Trump and ICE Gestapo wannabes arresting random people for minor administrative errors. Nobody sane wants to visit the US now.
Exhibit B, you assume higher GDP means something good. In the US, a good coffee, with tip and tax, can cost you $10. In France, it's 1.50-2€. GDP numbers would make you believe the US is 5-10 betters, but in reality, there's no difference other than Americans being scammed out of their money with very high prices.
Exhibit C, anything that happens in any of the US health insurance companies. Record profits, high market caps, etc. but you'd struggle to find anything of any value happening there.
