Yikes! Aren't we becoming a little curmudgeonly on the ol' RS Helpline? Seems to me, anymore, we spend as much time schooling posters about how they should ask questions, what homework they should do before posting, and even what name they should use in their profiles...not to mention the old stand-by, "Buy a guidebook"...as we do answering questions. I'm not saying that this counsel is never warranted, but sometimes it takes more energy to do the above than to just offer a thought on the question.
Here goes, Tiffany (I'll take a stab at one of your questions as a traveler to Europe 2x per year and blogger on travel, art and wine):
I believe that travel abroad does help offset (a little) the effects of the terrible economic situation in those locales (i.e. ensuring hotel staff keep their jobs, helping restaurants weather the storm, keeping some tax revenue coming in), but it really depends on where one is going. The reality is that the places most in need of the help are often not places on the typical tourist's itinerary. And things are so bad right now in some places that travel might do little more than prevent total collapse for a wage-earner or family. On the other hand, the benefits to travel, apart from sustaining local economies in some cases, are many and quite valuable: broadened perspectives, an appreciation for different cultures, a sense of the world as a small, close-knit place, the opportunity to understand yourself and your home culture more through exploring its roots or its distinguishing features to others...those benefits and a generally increased empathy with human beings not born under our American flag (which, by the way, I do revere)...these things seem as important during tough economic times (maybe more so?) than during times of prosperity. Those who can travel, should. Not exactly a moral imperative, and certainly not a panacea for the world's economic ills, but it's also more than good wine and a day at the beach. Just a thought.
