I often see Ultra-Nationalist (“Patriotic”) signatures on many forums expressing sentiments along the lines that the USA/Australia/Wherever is the best country on Earth, and if you don’t love it, then don’t let the door hit your ass on the way out.
That may have been a valid sentiment in the 1800s when there was (more or less) no such thing as “Immigration Restrictions” or “Border Controls” and anyone was pretty well free to move wherever they wanted (provided they weren’t a member of whatever the Oppressed Minority du jour happened to be)- but these days, you can’t generally simply front up in another country and decide you feel like living there unless you’ve completed a small rainforest’s worth of paperwork, had enough photos of you taken to cause an increase om the share price of Kodak Eastman, and been subjected to background screenings that would otherwise qualify you for a Field Operative’s position with MI6.
I often get a lot of “Australia’s Gun Laws are Communist-like in nature. You should come and live in the US” from people, too. Ah, were but it that easy.
Unless the US Immigration policy has changed since I last checked, it’s not simply a case of deciding “You know what? I want to live in a country where I can legally own a Machine Gun. Screw you guys, I’m moving to America!”
You need to have some skills (Computer Hacking Skills, Bow Hunting Skills, Ninja Skills… ), and engage in a process so tortuous it makes requesting information covered by the Official Secrets Act look like a Library Card application. In short, it’s a lot of hassle.
I imagine it’s the same if you want to move from the US to somewhere else.
Unless you’re a New Zealand Citizen, you can’t simply front up at Kingsford-Smith International Airport in Sydney and announce you’re staying permanently (unless you want to end up being held in a Department of Immigration Detention Centre somewhere, but that’s an unrelated digression), nor can you (assuming you’re not from the EU) simply disembark at London Heathrow and casually mention that Kent is rather nice at this time of year and therefore you shan’t be going back to Minnesota after all. Ever.
Anyway, to try and get myself back on topic: Overlooking the fact that if everyone who objected to the way something was done simply packed up and left, the country would rapidly end up being… well, not very nice, how do the people who want the naysayers to leave propose they actually go about it? Travel isn’t cheap, and there are formalities to go through- especially if the country you want to emigrate to really doesn’t want anyone else moving there, thanks all the same.
Yes, I know the “Love it or leave it” crowd aren’t always rational- but whenever people take that attidude, I tell them that if they cover my airfare, moving expenses, and get me a decent job, I’ll be on the next flight to London or Los Angeles. No-one has ever taken me up on the offer. Yet.
