If Europeans had some power on the immigration decisions of the US it would be stupid to make it worse for others when you could just accept it to be worse only for yourself.

On the other hand, a lot of people that have never experienced something do not even realize that that problem even exists or is real. Maybe experiencing a little bit of difficulty will enrich the vision of those.

Still, I think the point should be that with this pre-approvals you have end up with an easier immigration process and less worries for both sides (less time at immigration and not being turned down in the last moment).

OP didn't state they were happy. But reciprocity might be the basis to develop fair relationship. Otherwise how would Americans realize their behavior is problematic?

I mean, Americans haven't realised yet, I doubt that will change.

Yeah, the whole "this sucks; it should apply to everyone" mindset never made sense to me...

It makes it easier to gather support to change the situation. Good luck if you are in the minority with the problem.
