This economy in the USA is self-inflicted so the citizens certainly have themselves to blame. But there are also opportunities here too.
US trade shows are down. However, the world economy isn't the disaster for other better led nations that it is here.
There is plenty of work but it is overseas. Remember that the USA ranks #14 in world economies now. We are just below South Korea. The best markets are in China and India.
Rule #1 in Duck Hunting is go where there are ducks.
Trade shows are markets for producers. The USA is seldom a player in that area today. (Our current agenda appears to be "Borrowing our way out of Debt".) "Production" isn't a word used in political America in at least a year and more like three years since the new Congress of 2006.
The logic of having trade shows here is a going-away thing. Consumption for non-producers is retail. Trade shows are for business-to-business.
Magic to promote retail in the USA is perhaps the better choice. Restaurant magic is an example. Reality is that ultimately production feeds consumption. As America goes out of the production activity and concentrates only on consumption (as is the current agenda in the USA) limited success there is the opportunity. However, once the nation's savings is gone, there will be nothing to trade for consumption only. Plan ahead. It may mean seeking out the productive people in the world to serve. They are likely to not be in the USA.
