I would say the thing I hate the most about the USA is not unique to the USA. It's the belief that someone else should be responsible for rescuing you from your own mistakes in life.
The specific way I've seen this in the US is things like people's reactions to stuff like Hurricane Katrina where people blamed the president for people not getting the hell out of town when a hurricane was coming and not being able to wave a magic wand to rescue everybody. I have a feeling people in Asia that have seen Tsunamis blow through were probably laughing at us then. Those people did what they had to do and likely didn't spend much time bitching about the government not bailing them out.
I see it all the time in my job too as people walk off the job and then come back and want us to fill out their paperwork so they can get welfare or unemployment and then try to claim we are heartless or racist or whatever because we don't fill it out so their kid is going to starve. You had a JOB moron, and I didn't force you to walk off the job and leave somebody else to do your work as well as theirs. The people who had to cover for you should be the ones getting some sort of benefits, not you.
You can call me lazy, fat, unmotivated, privileged, disorganized, forgetful, clumsy, uneducated, ignorant, gluttonous, cowardly, etc. I won't likely argue with anybody on those points. But the one thing I am proud that you cannot accurately say about me is that I expect someone else to be responsible for me. I take my own actions, I face whatever rewards or consequences come about because of them, and I don't waste my time blaming others for my mistakes or crying about "unfairness" or "intolerance" or "inequality" or any of that when things don't go my way. I simply adapt to what is thrown my way and make the best of it as much as I can.
