It's not my country - harr harr! The U.S may not produce as much money as it produces value, but it still produces more value than any country in the world! That value is not going anywhere.
Seriously, don't be afraid. This is a media recession. If this were a real economic problem, companies would be tightening their belts, buying shares, merging, selling off stuff, and the vultures would be there pecking at carcasses. It's not happening. The papers make things sound bad, but imagine you didn't read the papers. When you go out, things are pretty much the way they always where.
Nike, iPhone, are all made in China. Levis are made in Latin America. I am not sure that will be counted as "made in U.S.A"
But I am sure we have made a lot of pornos because U.S. constitution protects them for the freedom of speech. And it is really risky for any people in Middle East to shoot porns than in U.S.A. . So probably this is one of few things that we make that poor men outside U.S. truly rely on.
Google is trans-national with development done worldwide
Boeing is trans-national with production worldwide
Ford is trans-national with production worldwide
Microsoft is trans-national with development worldwide
Apple is predominantly US based but trans-national
Nike manufactures in China or anywhere sufficiently cheap
Levi is the same
McDonalds gets its meat from Brazil and is trans-national
Coca-Cola is trans-national - in WWII Coca-Cola in germany was scarce, so the local franchisee developed Fanta as an alternative which made its way back after the war.
If you're talking about the kind of hard times where your economic needs are reduced to 1400 calories/day, a lump of coal to cook your millet gruel, and some shoes made of old tires, the US is at least a major food exporter.
There are less-expensive alternatives for all of the examples you provided. Take a look at what happened to each of those companies (which existed) back in the early 90s.
For planes, there's already a nice inventory of used aircraft backing up thanks to the latest airline bankruptcies. Do you think an airline will be buying new (or any?) aircraft if vacation and business travel drops off a cliff?
