I can tell you cant afford visiting other countries, that's why you dont know jackshit about other cultures and facts and you grew racist, a bigot and paranoid about the unknown.
It's not about cost. It's about common sense. First of all - the U.S. is the greatest country in the world. Why the **** would I visit a muslim 3rd world shit-hole when I already live in the greatest country in the world? Second, why the **** would I "vacation" somewhere that they can't speak English? A vacation is supposed to be fun, not challenging. I don't want to have to work for 20 minutes to communicate to some muslim slob that I want a glass of water. Third, whey the **** would I step foot on the land of a third-world country and surrender my constitutional rights?
From your post, it's patently obvious that you have never been overseas. Me? The Navy was kind enough to provide me with a lot of travel over the course of my career. And, I can tell you from personal experience that 80 percent of the people over there speak English. However, if you act like an ugly American and ask if they speak English in a loud, slow voice speaking English, most will say they don't and walk away. In some cases, they may sit there and mess with you for a while to see if you are going to try to speak their language before telling you they have to go.
However..........................I learned early on in my career that if I took a small phrase book (available free at the Quarterdeck), and tried to speak to them in their language, they would let me stumble around for a minute or two, then they would smile at me and tell me they spoke English. Made quite a few friends overseas that way.
Sometimes though, they would take advantage and mess with me. I remember one time in Spain I met up with a couple of guys who helped me find out where I was. They then asked me if I wanted to join them for a beer, and I said sure. Well, we walked into a bar, and the bartender was STUNNING. I mean she was flat out beautiful. I asked my new friends how I could compliment her on how she looked, and they gave me a phrase to say. I looked at the lady, and with a big grin, basically propositioned her for sex. She got REALLY upset, the dudes I was with burst out laughing, and she realized that they were messing with me by having me say inappropriate things, and we all had a good laugh.
