eh, there's a real trend here, but it's not an apocalypse
and it's not all of so-called "western society". It's mostly just decline in the US. Think of it like Britain.
Not long ago, they were at the top of the pile. Richest nation in the world, so much land the sun literally never set. But empire is an organism. It grows, it thrives for a bit, it declines. And it's not like Britain just disappeared from the globe. They still exist. They're just also significantly less important.
random people who happen to vote for a Republican or a Democrat aren't to blame, sure
but the actual Republicans and Democrats; the representatives, the party functionaries, the people who's checks are signed by the RNC or the DNC? Those people certainly deserve some blame.
