In other words, Oldsoldier, you've still got some industry left in your town.
The "post-industrial service economy" was not an accident. The think-tank people openly promoted it. Dr. Milton Friedman, who, contrary to his fictional reputation was no "free-market advocate", but on the contrary, one of the most gold-loathing "management society" central planners in US history, the man who invented the concept of wage withholding (and several other taxation policies he invented), openly advocated the wholesale offshoring of all our industrial capacity, and furthermore, hinted that the whole thing could be accomplished through an artificially over-valued currency.
What I have noticed is that those parts of the country that still have vestigial productive capacity fare the best in recessions. That's because, as you noticed, people still want to eat during recessions. On the other hand, the first businesses to lose all their customers (I was about to type "fail", but that's not necessarily true, since some businesses are bailed out regardless of customer demand or their own efficiency and success or lack thereof) are those that provide services that people can do for themselves, such as "day spas" and "doggy day care".
What you need to do to survive, is create a way to support yourself that doesn't rely too much on the outside economy. Now unfortunately you can not decouple-completely: you have to pay taxes in the national currency. Indeed, that is the primary purpose of having taxes and especially real-estate taxes, which are actually "rents". You can "thank" David Ricardo and Karl Marx for that little insight; it was their idea to use taxation as a means of preventing capital accumulation among the riff-raff, in order to establish and maintain a monopoly on capital. Another reason for having taxes is to distract attention away from seignorage (making money by charging interest on fractional reserves). If we didn't have taxes, the riff-raff would start wondering how government pays for its activities. In Hong Kong, where taxes are few and tax rates are low, they don't wonder; they enjoy the low tax rates and don't bother asking questions...
One particularly insidious form of "taxation" is inflation. Yet another reason for taxes is to create artificial demand for the national currency. If you didn't have to pay taxes, you could live fairly self-sufficient on your homestead, and if you just swapped a few goods and services with your buddies, you might not need ANY money, which is why the IRS considers that to be tax-evasion. In that case, you could opt-out of the national currency, and thereby avoid paying the inflation tax.
If opting out of the national currency were an option, then "the economy" would no longer be your concern. You could create an internal economy totally decoupled from the ravages of the external economy. "Inflation" and so-called "deflation" would not be issues for you; your fate would be dependent on your own productivity and efficiency, and not on what the rest of the economy is doing.
