Not everybody in the world speaks ENGLISH.
i'm not quite sure what you are saying. Are u saying that because business is so international that there is no point in learning a langauage?
if so, WHAT the HELL are u thinking.
The very concept that business these days is so internationalised and globalised means, that to really go somewhere, it is basically imperative that you learn another language. The majoiryt of Aust's trade is with Asia and if u speak an Asian langauge these days u r snapped up for the plummest commerce based jobs. These people go onto greater pay, higher positions, and a more interesting work life.
It depends what ur goals in business are- there is no point in learning another langauge if ur just going to be a small chartered accountant or some crap but if you intend to go onto the big time, which basically is not centred in Australia, learning another langauge is a huge stepping stone.
Without trying to sound too harsh, your comment reaked of anglocentrization (if there is such a word). what, do u think that everybody in the world speaks English, and if they don't they should learn it if they want to talk with you. Contrary to your assertions (shared by countries such as USA) there is a world outside yours that doesn't speak English.
In conclusion learning another language (esp Asian) is excellent for advancing your commerce careerthat is, if your aiming high.
