No, not the US as a whole, but perhaps the end of the insane and without reasonable measures Capitalism that it has spawned. This is the theorized late-stage capitalism, but it was brought to this level by a broken and out of control system, whereas the academic model of capitalism would have had certain mechanisms of balance to prevent exactly where we are. The system is too imbalances to work with all these corporations, conglomerates, and billionaires hold a disproportionate amount of the wealth, and keeping it from circulation. It just can't work this way, so some drastic shift to reduce or remove that will need to change.

Capitalism doesn't require infinite growth. This is some trite line that was invented on Twitter and became the common wisdom in online discussions about the failings of current national and global economic systems. It's not true. It appears to be true that the current model of capitalism favored the globe over requires infinite growth, but the current implementation of capitalism is not the same as it has always been implemented or will always be. There are more than enough legitimate criticisms of both capitalism writ large as well as current systems, we should be directing our ire through those arguments and not one that is factually false.

Good. Let's fucking get it over with.

Our entire economy is predicated on infinite growth, which doesn’t exist and isn’t possible.

You can sit in front of a computer using almost zero new resources while coding an application which you then sell to a megacorporation for 30 billion. The "inifite growth with limited resources" -argument doesn't hold.
