People do learn other languages, but at about the level Americans learn other languages: a few years in school, rarely able to carry on a conversation. Older people are more likely to be able to carry on a German conversation, but among younger people it's uncommon. If anything there's increasingly a little bit of nationalist suspicion about people who speak third languages, especially third languages natively. It's normal to be fluent in English and Danish, but if you're raised speaking another language at home, that smells of the dreaded "multiculturalism", and people may actually criticize you for raising your kids speaking a foreign language at home instead of fully assimilating into Danish culture and raising them in Danish. (Goes doubly if the foreign language is Arabic or Turkish.)
The other important point is how much you use a language. Americans simply don't have contact with languages other than English most of the time. You also see this effect in Germany where the English level is fairly low for speakers of a language that is so similar to English. And this because tv and movies get dubbed in Germany.
I'm probably biased, or maybe it's because i went to a smaller school system (graduating class of only 120), but there's not nearly enough available with regards to programming, statistics, finance (you should learn how to at least do your taxes while in high school), language development (foreign and speech), and writing (we really only learn boiler plate stuff). Instead we get more 'teaching the test' so schools can keep what little funding they have.
Pros:
- The 9 years that I spoke French in the classroom for every class except for English was enough to make the language stick. I'm 31 now, and I can still speak, read, and write French. My vocabulary is weak since I don't use French on a regular basis, but when I was in Paris, I had no problem understanding what was going on, ordering food, taking a cab, etc.
- I feel like having the 2nd language has made it easier to pick up other languages. I'm by no means fluent in Spanish, but when I was regularly doing DuoLingo Spanish lessons, I felt like things stuck very quickly.
- I also feel like some kind of structures in my brain from this help me pick up different programming languages. It seems like, compared to most of my peers, switching between new languages and learning new languages is generally a straightforward task for me, including weird ones like Erlang and Haskell. The majority of the effort goes into learning the concepts, not learning the syntax.
Cons:
- After graduating high school doing full immersion all the way through, many of my peers struggled with writing in University. I distinctly remember my first roommate getting an essay back and he was freaking out about the terrible mark he got. He asked me to look over it to see if I could see what was wrong with it. I read through it and just told him "Well... the problem is that you used English words, but you wrote it in French."
- Likewise, many of them had difficulties in math and science, where they understood the concepts very well from high school, but didn't have the English vocabulary to describe what they were doing.
All in all, I'm super happy that my parents made the choices they did, and that I dropped out of immersion before high school. I think, too, it helped a lot that I read a pile of English books growing up, both fiction and non-fiction, which hopefully helped supplement my English vocabulary while I was learning French at school every day. I was the 10 year old who held on tightly to his copy of the Peter Norton pink shirt book :)
Let's do some comparison. For kicks, and because I work with some Danes, we'll use Copenhagen. Denmark has about 5 million people. The state I live in, Washington, has more than 7 million.
From Copehagan, you can travel 28km and be in Malmö Sweden. Hope you know Swedish! Meanwhile, I'll still be in the metro area of the city I live in, Seattle.
Go 151km out and you can reach Stralsund in Germany. I'll be able to just reach the tip of Canada, since Seattle happens to be near the corner of the state. But if I go East, I'm still less than a quarter of the way out of Washington. And, of course, even taking Canada into account, I'm still surrounded by only English speakers.
Up to 251km, and now we've reached Kolobrzeg in Poland. Still mostly in Washington, though I can just reach the edge of Oregon. Everyone there speaks English.
At 392km, we can get to Kristiansand, Norway. Meanwhile, I can still be in Washington.
A 530km jaunt across the Baltic gets us into Lithuania or Latvia. That just gets me to Oregon, Idaho, and a bit of Montana because Idaho is so narrow.
Going the other way, a 784km paddle across the North Sea gets us to the UK. That gets me a little bit of the way into Nevada and California. 44 states are still out of reach.
804km will make it to France. That gets me to... still just Oregon, Idaho, Montana, Nevada, and California.
To get to a place where English isn't the main language, I have to go about 1,700km to Mexico. That distance will take a Dane well past Moscow.
To get to Florida, the last place I lived, I have to go about 4,000km. That distance will take our Danish friend to Sudan, Saudia Arabia, Novosibirsk, or well past the North pole. In fact, it will take them just about over the Atlantic all the way to Canada.
So, yes, I do wish I was multi-lingual. But I don't think it should come as a shock or be considered a failure that most Americans are when it lets us converse with all of the more than 300 million people that are in a several thousand kilometer radius around us.
Only surprise is that education systems around the world continue to waste so many years of people's lives trying to teach them additional languages when they're teenagers, instead of having done the bulk of the work when they were babies, the way that nature's been doing it successfully for tens of thousands (or more) years.
I know plenty of people whose language-learning strategy is basically, "Put myself in situations where I need to use the language and I can puzzle things out. If I get curious, maybe look something up once in a while." It's not quite like childhood acquisition, but neither is it a completely different process.
Sure, eventually you just have to use it. But as an adult learner, you can get going a lot faster by using your knowledge of other languages, understanding of rules, and so on, before jumping in, and it's not always practical for people to just take off and spend months or years in a foreign country in the hopes they'll learn a language while they're there.

My instructor chose to go full immersion, basically what children are subjected to. The other instructors took the grammar/vocab workbook route.
> Being fluent in three languages never seemed like a big deal
So the joke goes: three languages = trilingual, two languages = bilingual, one language = American
We never really discussed this when my son was born - it just happened, because doing it any other way was alien enough to not enter our heads. Seems to be the norm in Europe.
Yes, I struggle with French (his mum's German is pretty reasonable). I have a secret weapon though - I'm also native-fluent in Afrikaans, which I use when I scrape a shin, drive angry, or tease.
Being fluent in three languages never seemed like a big deal - my mother spoke seven. It is a big deal when you speak to a Brit about it, or to an American. I guess when you're used to chicken, beef might seem a little odd.
