Ah, yes, I've also heard that out of politeness the names of countries must have a good meaning (Meiguo, Yingguo, Deguo etc).
We are famous for "Stockholm syndrome": "Q: Hey, what's up with Matt? His Dad is on social security, his mom got laid off, his sister's kids get free school lunches, he collects federal financial aid for college, and he only makes minimum wage working at Walmarts. Yet he keeps talking about how we need to cut taxes for the wealthy and quit spending so much on social programs. A: Yeah, he thinks he's going to be a millionaire soon. He's got Economic Stockholm Syndrome." (Urban Dictionary)
