If you read accounts of what happened to the middle class in Argentina during and after their 2001 economic crisis, neither does the rest of it.
A whole lot of bad characters aren't going to like it when their monthly government checks stop showing up, and they'll be headed to collect the drug and alcohol money that Whitey owes them from anyone in the vicinity who still has any.
The proposed Army presence in urban areas isn't about shooting rebellious conservative patriots (their egos notwithstanding) it's about shooting the Crips, Bloods, and MS-13 types who threaten what remaining legitimate taxpayers the government will desperately need alive. Correcting the fallout from the Great Society, in other words.
If the world situation does not stabilize, I can see #2 happening. The US is dependent on foreigners buying our T-Bills. If all of a sudden we need to roll over a T-Bill issue, and we don’t have enough buyers, then either the government stops spending so much (unlikely) or the fed just creates money and we have hyper-inflation like Wiemar Germany or Zimbabwe.
My Wife reads a blog out of Argentina from people who went through this. I wasn't pretty. (wish I had the link)
Anyhow, these people who poopoo this as shear tin-foilery will no doubt be in shock if any of those scenarios go down.
Hey, Nobody expected Obama to become President either.
