For a country with a $29 trillion GDP america looks like a fucking dump

I have a fetish for futuristic architectural aesthetics and after traveling across Korea Singapore China where they have shiny skyscrapers and fast trains and clean public spaces, why the fuck does this country still look like it’s the 1980s lmao. What the fuck is the point of having an $80k GDP per capita and being the tech leader of the world. I’ve visited Chinese cities with a $7k per capita with way nicer infrastructure & cleaner public spaces. Can the US elite really not spare a tiny portion of their wealth to build modern infrastructure & public spaces for the poors? We’re gonna go into the 2030s with no high speed rail while multiple developing countries already have it.
