Yep. Here's how I'm doing it:
I got education enough to put me in a fairly recession-proof job that is also highly valuable overseas. I'm married to an EU national who can go back home any time he likes. We have bank funds enough to move there in a dire emergency. 
My employer recently had a smallish layoff, during which they dumped a lot of sales staff, but they kept R&D almost completely intact. Our competitors are even hiring, so some people are just quitting to go to the competitors, who are trying to catch up with us because we were early adopters of a new technology. 
We do garden, can, fish, cut wood out of the woodlot, etc. but it's more so we can save money to spend on other things instead than it is to live off of, offset our oil heat costs. And a hobby. My orchard will take three or four years before it starts paying for itself in any meaningful way. 
We have a well, it's beyond funky though. And awfully close to the outhouse. I calculated what we'd need to be self-sufficient, no way could we do it on two acres. The food crop is do-able with hydroponics and stuff, but the oil crop and fiber is not. Bamboo fiber maybe, but the processing is a real pain in the neck.
