Keep in mind that if the whole world really hated us, they wouldn't be beating a path to our door, and we would stop hearing stories of immigrants risking everything to start a new life here. I'm reminded of the time a few years ago when an anti-American demonstrator in the Philippines put this sign on the fence of a foreign-owned factory:
"Yankee go home! And take me with you!"
You touched on something that I have seen quite a bit though. For years I lived in a house where I was the only American--my housemates were non-American students, as were all the friends they brought over. Almost to a man and woman, these people HATED the US, but wanted to be here to take what they could. I'm not being the Ugly American At Home here, merely relating my personal experience, and I don't claim this is EVERY immigrant or legal alien's position. But I'm talking dozens of people I spoke with over four years, and I was truly shocked by the attitude. Those that didn't want to leave ASAP wanted to stay awhile, make some money, and go home, and had a tremendous amount of anger toward the US because (this was a very common theme) we have so much that we should share our wealth, while their countries didn't have anything like our wealth so they didn't owe the US a thing. It was pretty damned stunning, and after a couple years I tended to avoid their parties.
