Sorry, which part of my personal experiences was nonsense? Immigration is hard, and yes, I'm aware of challenges in the UK as I moved my spouse over there in 2014. Do you have an experience with immigration that you can speak to?
I think you're responding to a comparison I didn't make. My point wasn't that the US is uniquely difficult compared with the UK or Australia. My point was that legal immigration is difficult, stressful and often misunderstood, including for people who are clearly trying to contribute and follow the rules. I'm aware the UK system has become much harder since I used it, and I'm not disputing that. But "other countries are harder" doesn’t make my experience nonsense.
Your experience wasn't nonsense. Your expectations are nonsense. If you think immigrating to another country should be straightforward and easy, then it's your expectations that are wrong. I also immigrated to the US and it was just as tough, even though I came well before Trump and from Canada.
Is the goal here to be the same as others or to be better than others? The US immigration system is far from great at the best of times, but it's becoming worse over time.
It's not an ideal outcome it's a very non-enviable multi-decade process working menial jobs and being at risk of something benign like a traffic stop escalating to imprisonment at any time. This fantasy that illegals are living in luxury is how they boiled the frog on people who "did it the right way." They want to get rid of everyone.
