If you're talking about the USA, then famines would basically have to be involved. We're talking about a near-collapse of the system, where a significant portion of the proletariat is either facing death or has lost people close to them.
And I'm not talking about some minor famine here. I mean something on the scale of Wyoming just ceasing to exist because everyone starved to death.
I wish I was joking but thats kind of my gut feeling...Anything short of systemic collapse wont be enough.
So yeah it still can get much worse and it probably will. Really hope im wrong.
But im sleep deprived so maybe im just completely off.
EDIT Now, of course, if Trump really runs for a third term and declares himself president for life....that could speed things up. I just don't see most Americans waging a people's war until the situation gets completely and utterly fucked up.
I think we are in the last days of Rome but its not burning....yet.
