But on the individual level, being an english speaker can make it harder. I'm living in Norway. I've had a couple years of immersive language classes. Most of the population speaks English, and many assume to simply use that when speaking to me. The accent and all. Some Norwegians don't see the point of an english speaker learning the language here. A fair amount of the popular music is in English, even Norwegian bands. Television? Childrens tv is dubbed, but a lot of adult television is English with subtitles. Advertisements? half and half. Telemarketers? Often english speaking.
Some books never get translated. Right now, I'm shopping around for a Norwegian copy of The Hitchhiker's Guide. Luckily it is available in Norwegian: Unluckily, it doesn't translate as well so it is a little different. And I'll probably have to order it. The local comic store, where I would normally buy sci-fi or fantasy, mostly sells English books.
Yet for all this, I'm highly motivated. It is really hard to be a part of normal society without Norwegian because this is what folks use in their everyday life. Not everyone here is strong in English, especially older folks. Some workplaces are in English, especially in the tech field, but many aren't. I'm not in the tech field, so learning it is. I'm getting there slowly :)
It's not like English is the only useful language.
True, but in most of the U.S. the number two language isn't all that useful. Also I should add it's not just a matter of utility, it's also a matter of opportunity. I mean sure, if you go looking for speakers of another language you can find them, but it's not ambient. I hear many different languages spoken here in Seattle, but almost all of these speakers speak English well.
Also I should add that I'm not arguing against bilingualism, I'm just saying there are practical reasons why it is not so common here in the U.S.
Even in tourist-soaked countries like France, good luck speaking anything but French out in the boondocks.
Actually I'm not just being a smart-ass here, I do have a point. The major reason that so many Americans are monolingual is that learning a second language doesn't have much if any day-to-day utility, whereas in India a second or even a third language may have tremendous day-to-day utility.
