Sloppy argument 1: Languages with more speakers are worth more than languages with fewer.

Sloppy argument 2: You don't need to learn languages spoken by people that are good at English.

Sloppy argument 3: forgetting to factor in difficulty and similarity to other languages.

Sloppy argument 4: language X is spoken in more countries than language Y and has a higher total GDP so it's more worth learning.

The word value is in quotes because the real value of learning and using a language lies simply in, well, learning and using it. Since learning a language usually takes years and years, the only real criterion that should be considered before learning a language is whether you like it or not, whether this language appeals to you enough to invest years and years of your time learning it.In spite of this, however, languages are often pitted against each other where the value of one is measured against the other in terms of number of native speakers, people studying the language, cultural value, etc. You see this in lazy appraisals of the situation by parents or others that have decided that Language X is totally the language of the past and Language Y is the new must-learn language. Here are some signs to watch out for that might indicate that you're dealing with sloppy logic when someone tells you that Language X is out and Language Y is the next big thing. Chinese and German are going to be compared a lot in this post as Chinese is an example of a language that is being a bit hyped now while German is an example of the opposite, a language just as worth learning that has been ignored recently.This is probably the sloppiest argument of them all. Don't learn German, it's only spoken in Western Europe, don't learn Korean, it's only spoken in Korea. The argument is sloppy though because a mere comparison of number of speakers doesn't indicate anything about a language's influence. Let's take a look at the top ten spoken languages in the world as an example. The last one has been removed from the list, so try to guess which one it is.Chinese, English, Hindi/Urdu, Spanish, Arabic, French, Russian, Indonesian/Malay, Portuguese, and...?Hm, what could the missing language be? Japanese? Nope. German? Nope. Vietnamese, Korean? No again. The next language on the list is Bengali , one of the most spoken languages in the world with a total speaker population of 230 million. And how often does one hear an exhortation to learn Bengali instead of German or Italian, because there are so many people to use it with? Clearly the sloppy argument about number of speakers is the wrong one to use.A far better way to ascertain the "value" or influence of a language is to look at a few criteria:1: GDP per capita2: Status of the language in the respective countries and areas where it is used3: Press freedom, internet freedom, economic/human development in the countries where it is usedGDP per capita is much more important than total GDP or total population, because when someone tells you that Language X is worth learning because it "helps your career", what this means simply is that Language X is better than other languages at helping one earn more money in the end. Okay, so let's think about how the average person makes money. Is it through stocks, buying and selling land, creating companies...? No, usually not. The vast majority of us make money by working for a company, trading a certain number of hours a week in exchange for a certain amount of money. In other words, since most of us work in positions like these, the total number of high-paying jobs that a language has to be able to provide in order to be more worthwhile than another is:. It doesn't matter whether the language is spoken by one million or one billion, as long as knowing it makes the difference between getting and not getting that one job that pays well and it worth doing.Take Norway as an example. Norwegian is the easiest language for English speakers to learn , and it has the second highest GDP per capita in the world after Luxembourg. If knowing fluent Norwegian can help one get a job making twice as much money back home, then clearly the language has demonstrated its economic value in spite of being spoken by only 5 million people. On the other hand, Spanish is spoken by more than 400 million people throughout the world, but its value in the workforce (especially in the United States) is a bit iffy, since it's not all that rare a skill to have. Perhaps you are fluent in Spanish, but so are a few million immigrants who do not demand all that high a salary to work. This is not to say that Spanish is not a worthwhile language to learn, but it's not a language where simply putting it on a resume results in a higher salary.This is important because often languages have differing statuses in the countries where they are used - some will be official languages, some simply spoken by a large segment of the population, some will be seen as cultured languages by the population, etc. Spanish in the US and French in Canada provide a good example. Spanish is spoken by far more people in the US than French is in Canada (though not per capita, mind you), but French is an official language of the country and many government jobs require fluency in French. These government jobs start the employee out at a slightly lower pay scale than others, then give the employee a year of training in which he or she has to become fluent after which you have a cushy government job and are set. Fluency in French is also often seen as a sign of intelligence or status in Canada, more so than Spanish in the United States.Afrikaans is another interesting example. It is also another easy language to learn, the cousin of Dutch, and spoken by quite a few people.(12 to 16 million, maybe more). Unfortunately in South Africa it is technically only one of 11 official languages, and so many speak English so well that Afrikaans has to work hard to stay noticed, and even that is only in the western part of the country. Afrikaans is also still (unfairly) stuck with some of the baggage that comes with the legacy of Apartheid.: Chinese is a good example here of a language that is spoken by a large population and fairly influential, but still a bit sketchy. A few months ago riots occurred in Xinjiang / East Turkestan, the western part of China with a large Uyghur population. In response to this, the internet was cut off entirely . China also often cuts off access to sites like Wikipedia and others from time to time at a whim and without warning. This is quite a big deal since the majority of Chinese found in the world is spoken in the People's Republic of China; remove that country from the equation and there is little influence left. It also remains to be seen whether China will be able to improve its overall environmental footprint in spite of a rapidly growing economy.On the other hand, Germany and other countries where German is spoken are managing to do quite well here. Press freedom is not restricted, internet access is good, technologies such as wind technology, electric cars and passive houses are being given a lot of importance. Given all this, German is probably still a safer bet in spite of the hype Chinese has been given over the past few years.Let's get to sloppy argument 2.This argument is another sloppy one that has no basis in reality, and is often given by those that have spent a few weeks in Europe and are amazed at how "everyone speaks English". Yes, certainly a lot of people speak English in Western Europe when approached by a tourist needing help. But no, this does not mean that learning the language spoken there suddenly becomes a waste of time and effort. We'll take Norwegian as an example again, since Norwegians are some of the best English speakers in Europe. If you happen to have a very marketable skill then certainly it is possible to work in Norway while knowing only English. Otherwise, however, knowing the language is probably one of the best ways to make inroads into the country, to impress potential employers that you are a serious and ambitious potential employee. It's true that most in the office will still be able to speak to you in English, but a monolingual English employee is still the only one that is not able to answer the phone, understand the conversation by co-workers in the background, understand a rental contract by themselves, understand the news, know what the bus driver is talking about when he says that there's been an accident up ahead and they will have to take a right turn here instead of going straight as the bus usually does, etc. In other words, monolingual employees always require a certain amount of babysitting that bilingual employees don't.And besides, there are also jobs out there that require a knowledge of Norwegian - Microsoft hired a large number of beta testers fluent in Norwegian when creating the Norwegian translation of Windows 7.This is another area in which Chinese is overhyped at the expense of others. Check the comments section in any Canadian article on French and one is more likely than not to find a comment along the lines of "man, nobody speaks French anymore and French bilingualism is a waste of money. We should be teaching our kids Chinese instead".The reason why this is a sloppy argument is easy to see: Chinese takes a lot longer to learn for a unilingual speaker of English, and it helps less in learning other languages later on. The only languages that really become easier after learning Chinese are Japanese, Korean and Vietnamese, and this is due to a large historical Chinese influence as opposed to any real similarity between the languages. Leave that part of the world though and Chinese doesn't help to learn any other languages. Compare this to French: French is similar to Spanish, Portuguese, Italian, Romanian and Latin, and it has had a huge influence on English as well. It's even similar to German in a few respects (using the verbto make the past tense, -(German) in 1st person plural, etc.). It also takes less time to learn. This is important because most students do not become fluent in the first language they take up in school. Many learn one language for a few years, decide they don't like it and then move on to a different one later on. If you learned French in school and want to move on to Spanish or Portuguese, you're good. Same for learning German in school and moving on to Norwegian or Swedish later. Chinese...not so much.This isn't quite as sloppy as the other arguments given above since it requires a bit of thought to come up with, but it's still not quite accurate. It's seen often when the argument is given that Spanish is more worth learning than another European language because it's spoken in so many countries, especially in Central and South America. This is naturally a good argument when your goal is to travel or live in Central or South America. It's a bad argument though when one's goal is to simply find a higher paying job, or move to a different country in order to do so. The reason for this is that the GDP numbers here are not per capita. Indeed, the highest GDP per capita one will find in Spanish-speaking South America is Chile, and even that is only $10,000 or so. Compare that to Norway, where the minimum hourly wage is about $16.50 ($34,320 per year). Yes, the country is also much more expensive but compare being able to save some 10% of one's wages in Norway compared to other countries.Conclusion: this post is not meant in any way to sway you towards languages like Norwegian or German or anything else, but merely to attempt to make sure that you are not swayed towards a language you would not otherwise learn due to sloppy logic. It is always most important to simply learn a language that you are capable of putting in years and years of time into, and if that language is Chinese or Welsh or French or Bislama, then so be it. Just be careful that you do not find yourself a year or two later in the middle of a textbook of a language you do not particularly like, because your parents or friends or teacher or anyone else made a sloppy argument that seemed to be valid at the time but turned out to be little more than hype.
