the language and economic power..

it is about the language education-its impact on the economy competitiveness and the growth of language business. 

When the economy is strong, the language will be learnt by people other than the country(s) where people speak it as a native language. English has been the super power in the language followed by the countries i.e. the US and UK with English as the super power in the economy. This makes the business easier for these counties as the US or UK people do not put so much energy into its language education. At the same time it strengthen the economy power all the more. It also give more job and business opportunity for the language industry and related industry of these countries. Now Chinese is becoming one of the trends in some countries as the country gains economic power. I think Japanese has been one of the strong languages as the country economy has been strong but slightly fading away. But I wonder when its economy was strong in 70-80s if Japan optimised the opportunity to strengthen its economic power and the language industry(i guess not). 

there has been so far the model that first the country gains the economic power and later the language power. if any, i wonder if there is any way to regain the economy growth by putting more resource into language education. in a sense, if reversing the model is possible or not.
