Sure, airfares have climbed a little lately, but in general, travel to inexpensive parts of the world has never been more affordable for most people. When Mark Twain traveled abroad a hundred and thirty years ago, travel was only for the rich. When airfares were deregulated in the seventies, ticket prices started to drop all over the world, and to this day, if you averse to work and don’t mind living like a beatnik or hobo, you can find someplace in the world where people will be more than glad to help you do so. Dubai is not one of those places. But there are many perfectly delightful spots in Southeast Asia and Latin America where a modern-day Thoreau could wile away the hours, gazing at dust motes dancing a sun beam and watching the clouds float across the sky.
