I travel from Europe to the US on a regular basis (once a month) for work. It's getting worse and worse. They track everything about you. I get held up when trying to enter. They're asking me more and more pointless questions. Like where do you work, what kind of work do you do, when will you going back, when was the last time you visited, where do you stay. I can't book any internal US flights from Europe anymore, since they can't verify my European credit card anymore (this started last month). Welcome to the US, land of the guilty until proven innocent.
At some point I'm not going to put up with this Bullcrap anymore. I'm just going to stay in Europe. And you can forget about my business.
