The video is a shallow take because it pretends Americans have a say in how their country is run: infrastructure projects don't get built, healthcare systems aren't fixed, and education systems aren't reformed, because of deep rooted corruption and crony capitalism. Squabbling over PC and whether to rename military bases didn't stop the US from bombing half the planet into oblivion, so how could it have prevented them from building a high speed railway?
The bigger problem lies elsewhere. What the world liked about America was Hollywood, Coca-Cola, Mickey Mouse, Michael Jordan etc. The world's envy and love for American culture is what gave the US unimaginable power. But no-one likes the bible bashing, bomb dropping, mass shooting, child imprisoning sociopath USA.
China won when America forgot who it was.

This thread has the same premise as your last one... and no, the US won't challenge China if Americans stop being offended by everything. Countries are perfectly capable of creating more equal societies and building new railways.
What's incompatible is wasting all your wealth on useless wars and promoting policies that only enrich the few.
