I have a question. How prominent of a language is English where you live? Would it be possible to live there speaking only English or would a second language need to be learned?
The newer generation typically speaks pretty good English. I've been all across the Nordic countries (Norway, Sweden, Finland) and I have to say that compared to Western Europe, a lot more people speak English very well or are willing to (no offence to frenchies as I love 'em, but I could barely find anyone who would talk in English with me while in France; same goes for Spain). I live in Estonia, one of the Baltic countries, and while the level is still pretty high here, it's not as good as in aforementioned countries. So I can't really answer your question unequivocally. There are many factors that affect this:
-Here, people aren't really used to speaking English in day-to-day settings. Yes, majority can speak it well enough, but it comes as more of a surprise when you suddenly start using English. We don't have many immigrants here... duh, who would want to come here. Everyone wants to live in the Nordic countries! Which is also why up there people have no problems switching between languages.
-Some people don't speak English. What are you going to do with them? I mean if there's a situation where communication is necessary but is nowhere to be found. Creates unnecessary problems.
-It's easier for you if you can learn the national language. While learning a new language is not easy at all, it makes everything down the path easier. By the way, Estonian is not my mother tongue either, but it still is a lot easier to use that than force everyone around me to use some other language.
Bottomline is, yes it would be possible. Still not as convenient as learning a second language in my opinion. But definitely possible.
^it's harder than you'd think to leave a country and gain citizenship rights elsewhere (unless you have direct provable ancestry in a country with good entitlements and progressive citizenship laws)
I live on my own a long distance from where my parents live (same country, opposite coasts). I consider my pretty lucky for people in my age bracket, both in terms of situation and developments in life. I definitely had help getting through college and bad choices during it, but not overly so, my parents always tried to instill some level of independence in me (never had a CC tied to parents, always had to pay living expenses, paid my car insurance, etc..).
I'm sorry if my last sentence was confusing. I didn't mean to suggest that you should leave the US to search for better life elsewhere. I was just responding to Invisible Helper's comment trying to say that what he said doesn't apply to the whole world. You know, the US is not the only country on this planet?
Ask yourself how many 18-28 year olds you know who went to college got a really really good job right away paid off debts live alone successfully and have a perfect life? I know 1 he dropped out of college actually to save the insane debts. 30 years ago it would take 1 year minimum wage to pay off 1 year college now it's 4 years minimum wage for 1 year college and inflation and prices for apartments or housing, everyone needs roommates or become a couple who work together a lot
