I've been in the US for almost a decade now, never entered the country for any reason other than work, where I'm paid a pretty nice salary, have a passport from an otherwise ordinary country and can tell you this: I have been treated like a criminal almost every single time at the port of entry, being asked the same question multiple times, yelled at for giving more information than was asked, despite being asked that exact information later on in the interrogation, and sent aside for further questioning. This has been pretty standard in the time I have been here. Only in less than a handful of occasions have I been asked a few reasonable questions and been treated nicely by a CBP officer. The exact opposite applies to my experience entering, say European countries, while not being an EU citizen. It's always been a pleasure, and taken no longer than a couple of minutes worth of questions, if any questions at all.
