Should everyone have to learn at least one language at school?!

We are living in a sociaty where the information technology has been speedly developing and more new abilities we have to use have been invented . But wich abilities you should handle is depends on what condition you live in or where you are from . we all know that learning foreign language is very important in mongolia , while it is not so necessary in usa or uk. and in india workers who know computer and english are valued very highly.
Recent years in mongolia, people have being strongly required to know foreign language especially english not only in a work but also everyday life. You will see lots of posters and signs written in english when you go out and maybe you can`t see any of those written withouth english words or alphabets. Its strange the owners prefer writing their signs in english to writing in their own tongue and want to give name to their ownership in english. But we already got used to it and it seems to be normal. Also you need to know at least basic english to use computer , mobile phones, and new technics etc… therefore to learn foreign language you have to start at young age. Because it is easier to learn when you are young and older you are, it is harder to learn. So I think teaching foreign language at primery school is important and much needed. In the end I want to say that knowing english is main necessity not proffesion.
