I most certainly do hope I'm wrong.
That said, I've seen the handwriting on the wall, and the same story I saw leading up to 2008;
- Huge income inequality, getting worse
- Huge wealth inequality, getting worse
- Systemic problems that caused the last crash unresolved
- Unnaturally low interest rates increasing debt overhang
- Stubborn unemployment
- Stubbornly low economic growth
- Nearly 1/3 of all Americans live below the poverty line
It's just a matter of time, especially since the Republicans now in power want to keep on borrowing from the future while lowering taxes and thus not paying their way.
Wildcards include a coming real estate crash in Canada, multiple nations in the Eurozone have debt overhangs like ours and strains on our military requiring more money without forcing higher taxes or mass employment (conscription, volunteering for war, call it what you like).
