that might not help, so here's a picture of a pack of corgis on a beach, hope it helps: http://media.tumblr.com/b9vfl4b63eh5j0pmcEfbxxxGo1_500.png
I am sorry to be the bearer of bad news . . . but we are almost certainly on our own with this.
China and Mexico may give token assistance as they are able.
You are correct about our dependence on resources, but the US is only one of several markets we export to. I'm sure China and India won't mind buying our oil and trees.
Simply untrue. The debt to income ratios are about the same, but US households on average still have more assets and cash.
Also, given the dramatic drop in US housing values and only a leveling off of Canadian prices, I question your second point as well, at least looking forward.
To first order, this is great for you. Stocks are going on sale. You want to do your saving immediately after the massive crash, not before.
Of course, that's just the first-order analysis. The second-order problems are potentially, um, annoying: If the economy tanks you might not earn any money to save next year. And your joy at being able to invest in a bear market (because you've got plenty of time to wait for the recovery) might be dampened by the sight of your parents moving in with you to save money because their retirement fund just evaporated. (They don't have time to wait for a recovery.)
For example, depressed real estate markets can create high demand for rentals. You might be able to make money each month on a mortgaged property (a real novelty in Australia for example). And if rental demand is high, prices will probably eventually recover.
The issue is that a recession by definition means most people are worse off.
