I feel like I've been holding my breath about this stuff since about the turn of the century.
Amazingly, most systems muddle along so far, with one unbelievable patch pasted over another.
The amazing thing about such things is the amount of inertia that faith in the system has to keep things going for a time, yet when faith in the system is lost change happens quite rapidly, and sometimes violently. Look at Brazil over the past several days; they've been having economic issues for a long time, and have a government openly determined to suppress the trade value of the fiat currency for well over a year, but in the end it was a 10 cent hike in the price of public transit that was the trigger. No leadership to arrest, no common theme, just a million people across the country that suddenly all had enough crap at once. The United States has been running on public faith inertia since at least 2000, but the rash of federal scandals is severely undermining that faith. When that 'faith bubble' finally pops, what happens next is anyone's guess.
