Define "crash" -- what does a crash mean differently than a recession? Or depression? Or a bubble bursting (like, the housing market / lending market) ? What's the fear? Is it just that "crash" sounds scary? Or "recession" sounds scary? Or are there specific things you're worried about?
Maybe this is a great opportunity, too. Housing prices low, interest rates low. Mutual funds/stocks low. Time to buy and get a nice fat nest egg out of it later.
What "preparedness stuff" do you think is necessary here? The guns and ammo?!?!?!? The years supply of canned goods?!?!? The camouflaged cement bunker in the wilderness with the ma-deuces on the perimeter?!?!?!
Or ...
Wise, diversified, risk tolerant investments? And maybe a simpler lifestyle with minimal debt, living well within your means? And savings enough to get you through jobless times?
