I have read this thread about 10 times, commented and deleted, because I respect Glenda's opinions and yet on this one I respectfully disagree.
I find it sad that millions of people in this country are without jobs, have lost their homes, that many, many children go hungry at night in a country that many consider affluent.
I don't find it sad that not everyone wants to travel abroad.
I know many compassionate, tolerant people that have never left their immediate area. I know others that are world travelers and are the exact opposite.
I also know some that present their passports like scout merit badges, present company excluded.
I definitely think cost is an issue for many. I don't find a house or car a luxury especially if the car is necessary for work. Time off from one's job is another factor. Family concerns are another. Many spend what time off they have visiting or caring for a family member.
Many foreigners have passports for business reasons, so not sure how the numbers stack up for leisure travel.
Considering two of the most visited destinations for foreigners is Disney World and Graceland, not sure they are all coming over for an education in our culture and history. And yes both Disney World and Graceland are dear to my heart for reasons many are not aware of.
For those with the affluence to travel it does come down to choice and that is what is great about our country is we do have choices.
And if those choices are different from our own, well then that is the first step in tolerance.
