Here are some reasons I considered, feel free to add more:
- It's hard to be rational about quality-of-life issues. A salary is a number that can be compared, but QoL isn't, so people can't make decisions based on it
- It's actually hard for middle-class Americans to emigrate to Europe, for complex technical reasons
- Americans are afraid of learning languages, and the language barrier is a big factor
- American immigrants can't actually achieve the QoL that native Europeans have, for social reasons (hard to get promoted, make friends, etc)
- European QoL isn't actually that good, it just seems good on the surface. The well-dressed and healthy people I'm seeing on the streets are actually miserable
- Americans think of themselves as "temporarily frustrated millionaires". An American accepts lower QoL for a shot at one day making it big, even though most are going to be disappointed
To add to your QoL statement I feel as though European countries have a different kind of QoL. Here in the states the material quality of life is high. Things here are cheap compared to the rest of the world. Whereas in say, Germany, the social QoL is higher. People are more taken care of there and overall have less stress. Cities are walk-able, trains can actually take you where you want to go in a reasonable amount of time, a sense of community still exists. I think of lot of people from the US value the type of QoL we have here over what they have in various European countries.
I would guess the biggest factor is cultural: the US was always viewed as the place to immigrate to if you wanted a "good life", not emigrate from. That includes the language issue - other languages were rarely encouraged since there was enough geographic diversity and opportunity that it was't necessary, people came here and learned English, not the other way around. Those US citizens that emigrated were assumed to leave because they wanted to experience a foreign culture, not necessarily because of quality of life issues.
Most people just don't see it as an option because they don't know anyone who has emigrated.
A few (other) explanations:
* QoL is hard to be rational about, and is something that (I think) has to be experienced first-hand. European salaries are most probably lower for comparable jobs (they certainly are for high-wage workers) but pack more punch because of better social benefits and, depending on where you live, lower CoL. However it can be hard to convince yourself that 40 k€ in Spain affords you a better QoL than 80k$ in California unless you've experienced both. I mean, 40 is much less than 80, right?
* the "American Dream" is still a big part of the American (and global, for that matter) psyche. I would wager most Americans think the US is a place to emigrate to, not from. I don't know if many middle-class Americans would spontaneously envision emigrating to Europe. This is probably even more true for descendants of recent immigrants: if your family struggled to get to the US, why would you consider leaving?
* Ability to live abroad, in particular mastering a foreign language well enough to live and work in the country
* I'm not sure how well employability travels. You can work as a developer in just about any country but I think this is an exception. A medical diploma does not transfer well between countries (e.g. you probably need to start again as an intern, re-take exams, etc.), neither does a law diploma. More "middle class" jobs will have similar barriers to entry. E.g. if you're a plumber in the US and move to Europe you have to deal with different construction codes, installed base, local habits... Same thing if you're an auto mechanic: different car manufacturers, different regulations, etc.
I don't know why people from the US often, even knowing about their own country's strict immigration requirements, assume that they themselves can just pick up and move to any country they want (e.g. Europe, Canada, Australia, etc). 9/10s of the US population aren't in high demand jobs, most countries don't want you.
But as other have mentioned this is a very theoretical question. A software engineer will do just fine, like I did, while a restaurant worker might find it harder.
2. Cost. I do not thing you understand how unfathomably expensive it would be to move from North America to Europe. Heck moving around the States can be extremely expensive already.
3. Unfamiliar culture. The average American is steeped in American Culture and is ignorant of anything elsewhere.
4. No ties to Europe.
5. Desire. Americans are blasted every day about opportunities here. We constantly hear about immigrants coming here but we never hear about opportunities over there. Our news plays into this, as they only cover bad things, so if we hear about Europe it's epically bad.
It's not big stuff but rather a combination of a bunch of small stuff.
- Houses are typically older, smaller and most scrunched together. This might be normal for someone in Europe but it's jarring for an American who expects a house with a lawn and white picket fence.
- The cars are typically smaller, again not something that's objectively better or worse but different. American's are used to big cars and the compact car culture in the EU is also jarring.
These are just two examples but it comes down to just about everything. I am not saying the standard of living in the US is better than it is in the EU, it's just different, and that difference is why most Americans will never move to the EU.
Moving here requires the ability to be a kind of permanent outsider who nonetheless is reminded by the dominance of his culture on every corner. It's a strange feeling and not one that I think most people are prepared to deal with.
I think it answers most of the original question.
Are you sure you're seeing the "average European?" Europe is a pretty big, diverse place. If you're spending most of your time in the wealthier parts of town in a big city, you're going to see a very different Europe than the poor section of a rural village.
Anyways it’s not black and white even for me, and visas aren’t that easy to get.
- Family and friends are now an 8 hour flight and 6 time zones away. Staying connected is difficult, particularly given American rat race schedules. I don't have children, so this is a challenge but manageable.
- The visa -- among the easiest to get for Americans with no family ties to Europe -- took 5 months and TONS of paperwork. I had to lease an apartment for an entire year in order to APPLY for the visa. In total, it cost about $40k to get set up there. Most middle-class Americans don't have that laying around.
- The language/culture barrier is real, even in a place with lots of English speakers. I'm diligent about attending lessons and studying, but it takes time. Learning the culture is even harder and I quite regularly make a fool of myself in public.
- Above all, I've gained an appreciation for how optimized for convenience life in the US is. I dry my clothes outdoors on a line just like everyone else. This is alone is a nonstarter for most Americans I know.
Vacation is different than than permanently living there. In many ways there are more freedoms in the US, easier to own property, lower taxes, better economic outlook. Of course all of this depends on which county you're talking about since they are vastly different.
Immigration requirements are often strictest in the best areas, and often exclude those who would most benefit from stronger social support systems.
A European can usefully learn English before knowing what they'll use it for, pounce on whatever opportunity arises in the more impulsive US economy, make some extra money for some years, and then eventually return home to a lower cost of living. Going the other way requires more planning and more specific goals for no bigger a payoff than can be found domestically, which naturally filters out many people.
I think ultimately it's just a matter of opportunity. If people are generally comfortable with their life, why would they move? They will only do it if a fantastic 10/10 opportunity presents itself; there aren't many 10/10 obvious opportunities to emigrate to Europe for.
Because:
-the capital city is in Washington D.C.
- in a case of a war, Europe will be sacrificed
My sister and I have both weighed moving to Europe. The cut in paper salary vs. cost of living seems to be heavily in Europe's favor once you have 2-3 kids. When we get to that point, we may make the move too.
I have no idea where to start - fear the costs, bureaucracy, and so on. It surely depends on where you want to go... and changing your mind is likely incredibly prohibitive.
Anyway, more probably don't do it because it's nebulous.
Something to consider, too - six years ago I was upper-middle class, now I'm just hanging in there with inflation. External pressures put one in survival mode
