90% of Americans aren't hated. It's the top 10% that make the decisions that other countries hate. I'd bet that if you asked these 2 questions in this order, you'd take solice in the answers:
1. Do you hate the American ruling class?
2. Do you hate the average American?
The vast majority of foreign countries would say yes to the first and no to the second. They might even follow up with "we love the average American".
We mess around in foreign countries way more than necessary, and for that, they dislike us. Pretty much all of South America is the direct result of US influences for the last 200 years. The ones we don't like are the ones that stand up to our imperialism in favor of a true people's movement. We are the reason that Israel exists in the middle of the muslim world. We essentially took their land from them and gave it to Israelis following WW2. I'm not saying Israelis didn't deserve a place to live, but we did take it none-the-less. That creates enemies.
Jealousy is really far down on the list of reasons to not like America. Jealousy would cause most rational people to try and mimic us. Most of our enemies do not try to mimic us.
