I can empathize with your position (I recently lost my job), and truly hope things get better for you, but as for the economy as a whole, I don't think the entire pet industry itself constitutes a significant part of it to cause any widespread damage. There will still be things to ship, even fish to ship (the non-invasive ones) and things to sell, etc.
In response to another post about fish smuggling:
I think that the assumption that black marketeers would be any less proficient at packing fish and keeping them alive in transport shows a lack of knowledge of smugglers. I'm not pro-smuggling, but if the fish were worth enough for some people to break the law to sell them, those people are probably going to take the time to make sure they don't lose their investment. In my experience (I lived in East Africa for a while) Black Marketeers are usually the most expert, most talented, and most capable people in a given industry. I used to buy LEGITIMATE<--(please notice that word) goods from them just because I knew they'd be better quality, or the black marketeers wouldn't even bother with them.
If you really want to stop fish from dieing in transport, you should stop buying them from mass markets in Florida and SE Asia, or from stores that buy them in such bulk that they generally assume a 10-20% loss just from packaging.
