The US is 100% in a decline phase, but so are, many countries. Many of the EU ones , UK for sure and then you have other countries that have just been shit for, seemingly, ever.

A bit like how the dollar is shit, but it's still the least shit of the fiats.

I blame most of this on fiat, because abusing the money printer is what keeps problems going and gives the state power to wage war and fund socialist policies.

Comparing the fall to Rome is a bit incorrect though, because the (Eastern ) Byzantine Empire alone was in decline for like, 1000 years.

Instead of a fall, we have everything sucking a bit more and people having to live in their cars in now a normal thing because it's literally too expensive to live for may people.
